Amazing Colors in Yellowstone Caused by Algae, Bacteria and Microorganisms

Wyoming is a spectacularly beautiful state filled to the brim with eye-catching splendor. See some of the images I captured here.

Yellowstone National Park

A fantastic artist's palette of colors can be found in Yellowstone National Park all created by Mother Nature assisted by some of her workers consisting of algae and bacteria. The landscape is like no other place on earth.

The molten magma at the core of the earth is closer to the surface here causing all types of exciting and unusual effects. In most places on earth, the crust is about 90 miles thick before one encounters the magma, but in Yellowstone, only about 40 miles separate one from this fiery core component.

Never static, minor earthquakes frequently happen in this locale and the landscape one sees today will evolve into something different in the future. It has been an ongoing pattern for eons.

Discovery of This Area

Listeners did not believe the earliest explorer's accounts of what they had found in the land mass which we now call Yellowstone National Park.

Understandably people were probably very skeptical when being told of intense aqua, orange, brown, yellow, blue, and even green colors of water and land that seemed to emerge in this landscape resembling no other.

Putting these surreal descriptions together with the geysers, almost 300 of them, that were intermittently putting on their explosive show and it is no wonder that early explorers to Yellowstone were believed to be telling tall tales of fantasy.

Of course, before the 1800s, the Native Americans knew of this geothermic area because they had utilized this land for hunting and fishing. The bison, elk, bears, wolves, and other animals that still call this area home today would have provided sustenance.

Effects of Heat, Bacteria, Algae, and Minerals in This Environment

As you can tell from the picture shown above regarding the Chinaman Spring, the bubbling and steaming water is simmering at 202 degrees Fahrenheit or 94 degrees Celsius.

Average temperatures of the hot springs in Yellowstone are around 199 degrees Fahrenheit, and many varieties of bacteria (which are small one-celled organisms) can thrive in that sizzling environment.

Some of these thermophilic bacteria (species that thrive in the hot waters) develop long strands that can become quite colorful.

Algae are tiny plants that live in water, and much of it is also present in Yellowstone adding to the colorful display.

The color of algae is related to water temperature with the light-colored algae existing in the hotter springs. Algae seldom survive in temperatures over 167 degrees Fahrenheit.

Rich minerals that have been liquefied and brought to the surface by the superheated springs also assist Mother Nature in creating brilliant splashes of pigmented coloration within the national park.

Thus the array of the bacteria, algae, and minerals thriving in this acidic hydrothermal environment help to create this astonishing landscape.

Old Faithful and Thermal Features in Yellowstone

Comprising the palette for all of these rainbow colors (in which the bacteria, algae, and minerals have done their part) are the ever-present thermal features which include the geysers, mud pots, hot springs, and fumaroles.

Most people have probably heard of the famous geyser Old Faithful which has been emitting a stream of hot water at regular intervals for years.

Fumaroles are steam vents that express various gases some of which are sulfuric giving off that rotten egg smell.

Mud pots are mud puddles in which steam comes up from below ground and heats them, making them bubble. If these mud pots also have minerals in them, they become very colorful and are labeled Paint Pots for obvious descriptive reasons.

Porcelain Basin in the Norris Geyser Basin rests over a significant fault in the earth's crust. Yellowstone is the most volatile and hottest exposed area on earth!

Ever-Evolving Landscape

Many forested areas exist here. But as movements deep within the earth shift, some areas that once had healthy stands of trees give way to the ground becoming saltier and or acidic with hot waters taking its place.

These minerals and other components are drawn up into the tree, and it soon loses its battle with life.

Looking at the picture below, one can see a white band around the base of a now-dead tree that had absorbed nutrients detrimental to its life.

In this environment, nothing remains the same forever. Areas that were once hot and lifeless (except for the bacteria and algae) again become fertile for trees and other plants. It is an ever-evolving landscape within this national park.

Elevated Walkways

People walking through these more active geothermal areas within the park are admonished to stay on the wooden walkways. The elevated walkways are to ensure people's safety as well as to protect this fragile environment.

Who would wish to take the chance of suddenly being scalded by steam or hot water that might lie below the surface?

First U.S. National Park

Yellowstone was designated as America's very first national park on March 1, 1872, by then President Ulysses S. Grant.

Comprised of 3,384 square miles (8,765 square kilometers ) it provides a variety of scenery.

In addition to these colorful geothermal locations pictured here, there is much in the way of wilderness with mountains and valleys.

Hiking, camping, fishing, and photography would keep one entertained for as long as one might wish.

Lodging both in and outside the park is available.

Ancient volcanic activity shaped most of this part of the country. Learning about Mother Earth from this unique place on the planet can be exciting and fun.

Colorful Yellowstone National Park

Colorful Yellowstone National Park

The last photo shown above has scalloped edging around the intensely pigmented pool of water. These are from silica deposits that have turned into what is known as geyserite.

The intensity of color depends upon the light, the microorganisms present, and the particulates that are in the water among other things. Pigments within the microorganisms themselves also account for different colorations.

Hopefully, these pictures of the effects of algae and bacteria in Yellowstone will entice you to come and take a look at this fantastic color display for yourself someday. There is much more of Yellowstone to see!

Hi Dale,

I am sure that you and your wife will really enjoy getting to see Yellowstone in person. It is certainly an amazing site to behold!

Dale Anderson from The High Seas on September 08, 2017:

Glad you shared this with us, Peggy! My wife and I are trying to schedule a trip out there as soon as we can both clear our calendars. She is going to love reading this I am sure.

Peggy Woods (author) from Houston, Texas on August 06, 2017:

Hi Susie,

I sure hope that Yellowstone does not blow its lid so to speak. We would all suffer the consequences. It is a beautiful but at the same time eerie place to visit. Glad you liked this Susie.

Susie Lehto from Minnesota on August 06, 2017:

I have never desired to visit Yellowstone, but I love seeing photos and learning about the place. Steve Quayle recently published a new books with beautiful colorful large photos. He has photographed Yellowstone for several years and says that it has not changed and that there is no danger of it blowing. All is well regardless of the hype.

You sure do know a lots about the place, which I am pleased about. Thank you, Peg!

Peggy Woods (author) from Houston, Texas on July 10, 2017:

Hi Rajan,

I hope your wish to visit Yellowstone National Park comes true someday. It is absolutely amazing!

Rajan Singh Jolly from From Mumbai, presently in Jalandhar, INDIA. on July 09, 2017:

Awesome display of colors by nature. Would love to visit Yellowstone National Park one day if possible.

Peggy Woods (author) from Houston, Texas on September 29, 2013:

Hi Roberta,

It is fun to think what the first explorers must have thought when first seeing sites like this. It is other worldly to be sure!

RTalloni on September 25, 2013:

We live in an amazing world! Very much enjoyed your photos. It's interesting to think of how explorers managed without all of our technology and then of how they were not believed. It would be neat to have heard the conversations… :)

Peggy Woods (author) from Houston, Texas on July 24, 2012:

Hi sgbrown,

Glad that I could show you some of the amazing colors in Yellowstone National Park. See my other hub for more information and photos. Hope you can cross Yellowstone off of your bucket list in the near future. Thanks for your comment and votes.

Peggy Woods (author) from Houston, Texas on July 23, 2012:

Hi vocalcoach,

Nice that you were able to visit Yellowstone with your family when you were a child of 8. It is so striking a place that it is easy to see why it lingered in your memory. Thanks for the 5 star rating, your comment, votes and the share. So happy that you enjoyed my photos.

Peggy Woods (author) from Houston, Texas on July 22, 2012:

Hi Cyndi10,

"Evil brew of beauty"...interesting description of some of the sights in Yellowstone. It can get a bit smelly also because of sulfur content in some areas. It is one of the most active areas on earth with an ever changing landscape. Despite it's beauty, my mother was actually glad to leave that area. Thanks for your comment. Glad that you liked my pictures.

Peggy Woods (author) from Houston, Texas on July 22, 2012:

Hi Mary,

Yes, it is a good thing that they have built those raised wooden walkways because the earth's crust is very thin in those areas and one could end up with one's foot going through and into some boiling hot water! People are warned to stay on the paths in Yellowstone. Aren't those colors amazing! So glad that you liked this. Thanks for your comment, votes and share.

Sheila Brown from Southern Oklahoma on July 22, 2012:

Terrific hub! Absolutely makes me want to visit Yellowstone, soon! Is added to the top of my "bucket list". Wonderful information and beautiful pictures! Voted up and awesome!

Audrey Hunt from Pahrump NV on July 22, 2012:

Dear Peggy ~ This is a spectacular sharing of mother nature's paintings.

You are a stunning photographer! I enjoyed this lovely journey so very much. It took me back to a time when I was 8 years old visiting Yellowstone with my family. I was completely mesmerized by "Old Faithful." I gave this 5 stars and voted up and across (not funny) and will be more than happy to share this everywhere!

Cynthia B Turner from Georgia on July 22, 2012:

Hello Peggy, Your photography is wonderful, but the pictures look like an evil brew of beauty. Thank you for giving us so much information and for sharing your pictures.

Mary Hyatt from Florida on July 22, 2012:

I really enjoyed this Hub about the algae and bacteria and the colors they have created in Yellowstone National Park. Good thing they built those wooden walkways so people can safely get up close to the sights. I want to return and read more of your Hubs on travel out West. You did a wonderful job on this Hub relating this subject; your photos were wonderful

I voted this everything except funny, and I will share.

Peggy Woods (author) from Houston, Texas on February 18, 2012:

Hi alocsin,

Yes...aren't the colors incredible! Yellowstone National Park should be on everyone's list of places to visit if possible. Thanks for your comment and votes.

Aurelio Locsin from Orange County, CA on February 18, 2012:

Incredible that something so small can create such beautiful imagery. It's great that your photos were able to capture their glory. Voting this Up and Beautiful.

Peggy Woods (author) from Houston, Texas on February 10, 2012:

Hi oceansnsunsets,

So happy for you that you got to see the fabulous Yellowstone National Park in person. As you say the geology of the place is fascinating and those colors...amazing! Thanks for your comment.

Paula from The Midwest, USA on February 10, 2012:

Hello Peggy, we were able to go and see Yellowstone for the first time this last summer. I was so wowed by what we saw, and the colors were very amazing! Great hub here, thank you so much for sharing it and giving me a little big of time travel back to where we were.

I love the geology of that place, and the history, and I know that I haven't begun to scratch the surface. Your hub here helped in that regard, thank you.

Peggy Woods (author) from Houston, Texas on November 09, 2011:

Not sure what you meant, but some say that any publicity is good publicity. Hope you enjoyed the pictures of the amazing colors in Yellowstone National Park.

gggggggggggggg on November 09, 2011:


Peggy Woods (author) from Houston, Texas on October 09, 2011:

Hello JSParker,

Isn't traveling fun! Nice to see things out of the country but also nice to see what lies within our own borders. Our National Parks as well as State Parks and National Monuments are all a delight to see. How many of the National Parks did you get to see besides Yellowstone? Thanks for leaving a comment.

JSParker from Detroit, Michigan on October 09, 2011:

After focusing more on travel abroad, we did a 30 day trek through American National Parks including the queen of them all, Yellowstone. Looking at your pictures brings back that delightful experience. Your hub is beautifully done and well laid out. An example to emulate. And still HOT after one year. Very impressive.

Peggy Woods (author) from Houston, Texas on October 06, 2011:

Glad to hear you liked the pictures of what algae and microorganisms cause in Yellowstone. The colors are amazing!

Bobby From The Future on October 06, 2011:




Peggy Woods (author) from Houston, Texas on August 04, 2011:

Hello livelonger,

So true! It is amazing the colors created by algae, bacteria and microorganisms in places like Yellowstone and elsewhere. Thanks for the visit and comment.

Jason Menayan from San Francisco on August 04, 2011:

This is stunning! What gorgeous shots. I've never been to Yellowstone, but my parents went there a few years ago and loved it. I have a friend who went to a similar lake (I think in Indonesia) where the minerals, bacteria, and algae created 4 colors in the same lake. Nature really creates some awe-inspiring work! :)

Peggy Woods (author) from Houston, Texas on August 04, 2011:

Hello leahlefler,

Your kids will enjoy Yellowstone as much as you did and you'll get to enjoy it all over again when you take them there. It truly is an amazing spot on this earth! Thanks for your comment.

Leah Lefler from Western New York on August 04, 2011:

We went camping in Yellowstone when I was sixteen years old (I won't mention how long ago that was, haha) - it was one of the most amazing experiences I have ever had. The wildlife, the sapphire pools, the boiling mud... it was just spectacular! Beautiful hub, and I can't wait to take my kids there (some day)!

Peggy Woods (author) from Houston, Texas on May 26, 2011:

Hi Rose,

You would have a ball photographing the sites in Yellowstone with your interest in photography. Such intense colors and interesting vistas to be seen there! If you go back there it will be a treat to see what you photograph. Thanks for your comment.

Rose Kolowinski on May 26, 2011:

Another beautiful hub, Peggy. I have been to Yellowstone but that was before I became serious about photography, so I have to go back someday. Thanks for sharing your colorful photos!

Peggy Woods (author) from Houston, Texas on May 11, 2011:

Hi leeroper,

Yellowstone National Park is a wonderland of colorful areas as you can see from these pictures. Amazing to see all in one area of the country. So nice that Yellowstone is protected as a national park for all to see and enjoy. Thanks for your comment.

leeroper from UK on May 11, 2011:

I had no idea of the array of colors in Yellowstone, now I want to watch a HD documentary of Yellowstone.

Peggy Woods (author) from Houston, Texas on May 09, 2011:

Hello kittythedreamer,

I don't have any more microbe hubs per say...just loved the colors in Yellowstone caused by algae, bacteria and other microorganisms which caused these amazing colors. I come from it more from an artistic point of view, but thanks for your comment. Will check out your hub.

Kitty Fields from Summerland on May 09, 2011:

What a wonderful and educational hub. I share in your interest with microbiology and the microorganisms that make up our planet. Thanks so much for sharing this information with the public. Keep up the great work! I can't wait to read more of your microbe hubs! Here's one of mine, if you are interested:

Peggy Woods (author) from Houston, Texas on May 09, 2011:

Hi KenWu,

Yellowstone is truly an amazing place with such colorful landscapes due to the interaction of the hot steamy water just below and at the surface plus the algae, bacteria and microorganisms that create an artist's palette of colors. Glad you liked this.

KenWu from Malaysia on May 09, 2011:

It's amazing. Thanks for the quick tour :)

Peggy Woods (author) from Houston, Texas on May 02, 2011:

Hello Knightheart,

Our National Park system is truly wonderful and I agree with you that places like Yellowstone need to be preserved for generations of people to come. Glad that you liked these pictures. Thanks for your comment.

Knightheart from MIssouri, USA on May 01, 2011:

Wow, I almost forgot the beauty of Yellowstone. Was there about 20 years ago and seeing God's creation was just breath taking. The beauty is almost indescribable! I pray that this country takes strong steps to protect these national treasures and preserve God's work for future generations! Thanks for the reminder of our beautiful country!!!

Peggy Woods (author) from Houston, Texas on March 19, 2011:

Hello Eiddwen,

The colors created by algae, bacteria and other microorganisms in Yellowstone are absolutely amazing! A photographer could spend years there capturing the scenery as it is ever changing and evolving. So happy to hear that you enjoyed this look at some of what can be found in Yellowstone. Thanks for the comment.

Eiddwen from Wales on March 19, 2011:

Wow another rare treat and it's no wonder that it has such a high rating.

Another one to bookmark for my armchair travelling days.

Thank you so much for sharing Peggy and take care


Peggy Woods (author) from Houston, Texas on February 23, 2011:

Hello again jaclin,

Hopefully Yellowstone won't erupt in our lifetime or many lifetimes to come. There are some prognosticators that say it would not only change lives in North America but all around the world. The earth's crust is the thinnest there in the world and the moulten magma closer to the surface. Makes for beautiful pictures of how the algae and bacteria affect the colors and let's just hope it stays that way! Thanks again for the comment as you seem to be doing some armchair traveling through my hubs. Appreciate it!

jaclin on February 23, 2011:

Again Peggy - thank you for an inspiring hub... Yellowstone was on our schedule last year when we planned our road trip - and it was certainly an amazing place to visit... and just amazing to consider how it all happens to be there - not being a person who understands the geology of it all - it was just amazing to stand within it all in awesome wonder...

...your photographs and writings are making me wish it was 12 months ago - when we were busy planning our trip - but if that was the case we wouldn't yet have seen all that we did!!!

Thank you again for a fantastic hub... in case I wasn't yet hooked - I am now...

Peggy Woods (author) from Houston, Texas on February 14, 2011:

Hello AskAshlie3433,

So happy to hear that you enjoyed these pictures and hub about the algae, bacteria and microorganisms that create amazing colors in Yellowstone National Park. It is certainly a unique and interesting place to visit! Thanks!

AskAshlie3433 from WEST VIRGINIA on February 14, 2011:

This is a really great hub. I love the pictures. Sure is a lot of good information Peggy. You always give such a good presentation, setup on your hubs. Best to you.

Peggy Woods (author) from Houston, Texas on November 13, 2010:

Hello Mott-StenersonPhD,

It is wonderful when one has the time to tour the country by car. One can stop in little out of the way places that might have gone undiscovered were it not for passing the area in person.

As you year! Yellowstone National Park will await your discovery. The colors are absolutely amazing! These pictures give you an idea...but just wait until you see this in person!

One advantage to viewing Yellowstone this sulfur smells! There is some of that in places.

Maybe you can write about your visit next year?

Mott-StenersonPhD on November 13, 2010:

Great hub and pics Peggy! We took a long car tour this past summer and planned to go to Yellowstone, but ran out of time and energy. Now that I have seen your pics, I want to go next year for sure. I guess that will be our first stop - can't wait.

Peggy Woods (author) from Houston, Texas on October 16, 2010:

Hello deepak tyagi,

Happy that I could share these pictures of what algae, bacteria and microorganisms create in Yellowstone National Park with you. Thanks for the comment.

deepak tyagi on October 16, 2010:

i, very impress this images

Peggy Woods (author) from Houston, Texas on August 01, 2010:

Hi Billy,

Algae is a tenatious life form that has undoubtedly been around for millions of years. Not good for the environment? Guess I will have to look that up unless you come back here to answer. I know that I battle with it occasionally in our bird bath. A good pressure wash takes care of it for a while. Yellowstone is an absolutely amazing place with all the colors from the algae and bacteria. Unearthly in a way...!

billyaustindillon on August 01, 2010:

Those blooms and greens are awesome colors. I have seen a few algae blooms - they do look amazing though of course not a good thing for the environment. As always great images Peggy.

Peggy Woods (author) from Houston, Texas on July 25, 2010:


Actually one could spend weeks or even longer if one wished to see all that Yellowstone has to offer in each season of the year. Have now linked your beautiful hub about Yellowstone to this one.

Charlinex on July 25, 2010:

Peggy, your wonderful hub reminds me that I have missed so much in Yellowstone. I should look for another opportunity to go back for more. :)

Peggy Woods (author) from Houston, Texas on July 02, 2010:

Hi suny51,

That is a fine compliment indeed. Thank you! It is not hard to talk about things that I find beautiful and so much in nature offers it up for anyone willing to look and listen. Yellowstone National Park has so much of it and in this hub I only focused on the beautiful effects of algae and bacteria. There is much more, believe me! It is no wonder that it was named one of our earliest of National Parks!

Peggy Woods (author) from Houston, Texas on July 02, 2010:


Enjoyed my wine and hope that you enjoyed your Romulan Ale as well. If all interactions were as pleasant as this has been, we earthlings should be casting our eyes outwards with great anticipation. :-)

suny51 on July 02, 2010:

Hello Peggy you really know the art of turning any thing in to beauty with an artistic touch, that is sign of a some one who has deep love for life and its beautiful angles.Great hub.Thanks

lxxy from Beneath, Between, Beyond on July 02, 2010:

Take a swig for me. I'll do the same with my Romulan Ale. Be well, Peggy. Will all wellness, and experience nothing but.

Peggy Woods (author) from Houston, Texas on July 02, 2010:

OK Ixxy,

Think I'll go drown my sorrows tonight in a nice glass of wine. Won't cure anything but will mellow my mood. Nice to know that even those from afar ( you ) share in our sorrow.

lxxy from Beneath, Between, Beyond on July 02, 2010:

I, too, am sorrow filled.

Especially as I observe oil-slicked rain and carcinogenic chemicals rain down on birds, humans, plants, and all that can be called natural.

A very painful experience. is such an oscillation of existence, as we've discussed.

Peggy Woods (author) from Houston, Texas on July 02, 2010:

New technologies may have been given a boost...but many people's current livelihoods will probably have been given a death sentence due to this BP oil spill. I realize that you are taking the broader perspective from time and space and I guess living in Texas and being more "earth bound" at the moment I am more sorrowful about the immediate effects.

lxxy from Beneath, Between, Beyond on July 02, 2010:

I agree. :)

And I think life will flourish, again! In time. And mistakes made will be rectified. And who knows, new technology may have just been given a boon.

Peggy Woods (author) from Houston, Texas on July 02, 2010:

OK, I get it. Lessons may be learned and we may adjust some things going forward from this horrific oil spill in the Gulf of Mexico...but they come at a terrible cost to the environment, sea animals, birds, and people's livelihoods. As a casual observer from sure you could cite many examples of the twists and turns throughout history of things that altered our modis operandi.

At least Yellowstone survived all those fires of some years ago and the algaes and bacteria are still doing their amazing coloring job.

lxxy from Beneath, Between, Beyond on July 02, 2010:

Lessons learned hard can be lessons remembered for years, which are always great.

Had I stopped the Titanic, how many more senseless deaths would there have been because of a lack of life boats?

There's always a choice, a cost, a point to be made.

Peggy Woods (author) from Houston, Texas on July 02, 2010:

That is indeed sad! Am sure that you could help tremendously with a little exercise of your powers. :-)

lxxy from Beneath, Between, Beyond on July 02, 2010:

Unfortunately, any drastic action on my part would incur a new temporal dimension. I'm already wanted by the time coppers for meddling once, so sadly I have to lay low for the time being.

Peggy Woods (author) from Houston, Texas on July 02, 2010:

Hi Ixxy,

As long as you remain friendly and quiet...what better to ask of an alien neighbor? Please be kind to Texas and if you can help clear up that oil spill instead of just "watching" have my vote! :-)

lxxy from Beneath, Between, Beyond on July 02, 2010:

I'm here...for now. But yes, I do like to keep quiet and observe from a distance. ;)

Especially Tx. ;D haha, I kid, I kid.

Peggy Woods (author) from Houston, Texas on July 02, 2010:

Hi Ixxy,

So happy to hear that you liked these pictures of the algae and bacteria creating the amazing colors in Yellowstone on planet Earth in this solar system.

Are you keeping an eye on us from afar? Hahaha!

lxxy from Beneath, Between, Beyond on July 02, 2010:

Such lovely sites on your planet.

And in your solar system, in general.

Thanks for sharing! :)

Peggy Woods (author) from Houston, Texas on December 25, 2009:

Hi Ethel,

Yes...the algae and bacteria in Yellowstone along with the heated pools of water do create some amazing images. I always have fun capturing pictures for my photo albums. Coming in handy for reference material now that I am creating these hubs. Thanks for the comment.

Ethel Smith from Kingston-Upon-Hull on December 25, 2009:

Fabulous images Peggy

Peggy Woods (author) from Houston, Texas on December 22, 2009:

Hi Kathy,

That sounds familiar. I was so young when my family visited Mount Rushmore and all those sights. I still have memories...but would love to revisit as an adult. Glad that I could rekindle memories for you of your Yellowstone visit many years ago. Thanks for the comment.

Kathy Rimel on December 22, 2009:

I was at Yellowstone many,many years ago and was not old enough to understand the whole process which creates this great natural wonder. Now I will have to go through all the old pictures and see if I can find the ones we took at Yellowstone and look at them again. Thanks for the trip down memory lane.

Peggy Woods (author) from Houston, Texas on December 22, 2009:

Hello midnightbliss,

You are most welcome for this virtual tour of a portion of Yellowstone. Much more to the National Park than just this area...but this is particularly colorful due to the effects of bacteria and algae. Thanks for reading and commenting.

Haydee Anderson from Hermosa Beach on December 22, 2009:

this really is an interesting hub with beautiful colors. thanks for the tour in Yellowstone

Peggy Woods (author) from Houston, Texas on December 22, 2009:

Hi James,

Hope that you also have a Merry Christmas with your wife, cute little dog and others you love. Happy that you liked these pictures taken in Yellowstone. The colors created by the mixture of algae and bacteria, etc. are truly spectacular. Thanks for commenting.

James A Watkins from Chicago on December 22, 2009:

Spectacular photographs, Peggy. This is one of my favorite Hubs you have created. I appreciate the excellent explanations as well.

Merry Christmas!

Peggy Woods (author) from Houston, Texas on December 22, 2009:

Hello Dink96,

Sounds like you have some great memories of your own having spent the night in Yellowstone and seeing Old Faithful at night. Spectacular! As to the air...just part of the aromatic memory! Ha! Thanks for the comment.

Dink96 from Phoenix, AZ on December 22, 2009:

Great hub and breathtaking photos. And let's not forget the "air" of Yellowstone. I'll never forget my first impression after having seen all these fantastic pictures of the park when we stepped out of the car and breathed in! :-) Seriously though, it is truly one of the most majestic places on the planet. We stayed at the Snow Lodge at Old Faithful Inn one night and were able to go out to the geyser in the middle of the night and watch the eruption! I shall always have great memories of that trip. Thanks for this hub.

Peggy Woods (author) from Houston, Texas on December 21, 2009:

Hi Ben,

If you like to paint, the colors in Yellowstone due to the effects of the minerals, algae and bacteria would certainly inspire you. Of course, the lighting...time of year, etc. would all add addtional features to the color palette. So happy that you liked this hub and hope that your wish becomes reality for you someday. Thanks for the comment.

Ben Zoltak from Lake Mills, Jefferson County, Wisconsin USA on December 20, 2009:

Loved it Peggy, thanks for bringing me there. Great research and fact finding. It almost reminds me as if you are walking on a constantly evolving volcano! Great pictures too, I wish I could go there and paint for a year.

Peggy Woods (author) from Houston, Texas on December 20, 2009:

Hello The Old Hack,

Hope that you fulfill your wishes and get to Yellowstone someday. If you looked at my other hub on the same subject, you would have seen much more of that area. Yellowstone truly is a wonderful place! Thanks for the comment.

The Old Hack on December 20, 2009:

Amazing place. Must add it to my "things to do before I die" list.

Peggy Woods (author) from Houston, Texas on December 19, 2009:

Hi Candie, you have camped there. Lucky girl! We only spent two days there sightseeing and were staying at Cross Creek Ranch in Jackson Hole. So accounting for the commuting time, we only saw things on the figure 8 route through the day with a tour bus and the other with a rental car on our own.

The sulfur smell is really strong in places like pictured here in this hub...but not everywhere in Yellowstone. I did another hub showing more of Yellowstone National Park. This one was focused solely on the colors created by the bacteria, algae and minerals in the hot springs and mud pots areas of the park.

So happy this hit on one of your favorite places to vacation. Have you written a hub about it from your perspective? If not, you should. We could link them to each other! Thanks for the comment, Candie.

Peggy Woods (author) from Houston, Texas on December 19, 2009:

Hello truth from truth,

Hope you do get to see Yellowstone someday. Thanks for reading and commenting.

You have now hit one of my MOST fave places to be.. Yellowstone. It is spectacular and your picures only cover it a little. What folks are missing is the smell of Sulfur.. (rotten eggs) and the buffalo poop near your tent at night.. and the sounds of wolves in the distance and the way the steam from the hot springs floats over the roads and valleys in the early morning light. Nothing short of magical! Thank you Peggy.. this place is heaven for me!!

Really nice hub, great pictures. I would like to go to Yellowstone one day.

Hi Dolores,

Yes, it is rather like seeing something on a world unfamiliar to us here. Some scientists that are studing the bacteria in Yellowstone think it might be something similar to what might have been on Mars which would prove that there was at least one form of life on that planet at some time. Very interesting! Did your son get to spend any amount of time in Yellowstone? Did he tell you about the sites like this? Thanks for the comment.

Dolores Monet from East Coast, United States on December 17, 2009:

No wonder people didn't believe the first reports. What an unbelievable place and so beautiful too! I love the photos. My son was out there this past summer and was quite impressed.

Hi dahoglund,

Thanks for the comment. This copied twice for some reason.

Hi dahoglund,

Nice that you at least stopped in Yellowstone to see some of the highlights. It is a huge park and we pretty much just saw the highlights also...but spent two days of our time doing that. Happy to report there were no earthquakes in Yellowstone while we were there as your friends experienced. Would rather give that experience a pass. Ha!

That wedding in California must have been fun.

Peggy Woods (author) from Houston, Texas on December 17, 2009:

Greetings Hello, hello,

I'm in total agreement with you in that nature can be so beautiful and offer such stunning sights such as this found in Yellowstone. We did have fun as you suspected. Thanks for the comment.

Greetings lovegg,

So happy that you liked this hub about the effects of algae and bacteria creating those amazing colors in Yellowstone. Thanks for reading and commenting.

Yellowstone and Old Faithful I do remember seeing years ago. We were on our way to my brother's wedding in California. He and some roommates rented a house in the Hollywood Hills right above the Hollywood bowl. We were a bit hurried to get there but we did stop at some place to at least take a look and some pictures.

A friend of mine was camping in Yellowstone beck in the 1960's (I think it was) and was woke up by an earthquake. It was quite and adventure for them.

Hello, hello, from London, UK on December 17, 2009:

Fantastic, absolutely unbelievable. Nature is so beautiful and plentiful. Thank you so very much for showing and sharing. You must have had a time of your life.

Have a nice day!

Hi Frieda,

I too love what I have seen of Wyoming. Spent two weeks there on vacation years ago and only two of those days were sightseeing in Yellowstone. But as you say...sights like these become etched in our memories. Have you written about your stay in the Tetons?

Frieda Babbley from Saint Louis, MO on December 16, 2009:

Yes, I have. It was on our way from Colorado to Washington State. We stayed the night there. Unfortunately didn't have too much time to stay, but what we got to see was beyond belief. We had most of it on film, but who knows where that is now. It was 13 or 14 years ago and I remember it as if we were just there. I love Wyoming period. The Tetons are gorgeous. We did have an extensive stay in the forest there one summer.

Peggy Woods (author) from Houston, Texas on December 16, 2009:

Hi Frieda,

As you say, the colors are unbelievably gorgous in this geothermal area of Yellowstone aided by the algae and bacteria not to mention the minerals. Have you seen it in person? Thanks for taking the time to comment.
