Yellowstone National Park

An absolutely amazing 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 interesting 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 separates one from this fiery core component.

Never static, minor earthquakes are frequently felt in Yellowstone and the landscape one sees today will evolve into something different in the future.

This has been an ongoing pattern for eons of time.

From what I have read, the earliest explorer's accounts of what they had found in the land mass which we now call Yellowstone National Park were not believed by listeners.

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 prior to the 1800's the Native American Indians 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 Yellowstone home today would have provided sustenance for the Indians.

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 love and live 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 exists in temperatures over 167 degrees Fahrenheit.

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

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

Yellowstone is so large that it is good to read up ahead of time and know where you wish to spend your time.

 

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 Old Faithful...the famous geyser within Yellowstone that has been expressing a stream of hot water in regular intermittent fashion for years.

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

Mud pots are literally mud puddles in which steam comes up from below ground and heats them up 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.

Many forested areas are within Yellowstone.

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 first picture to the right, one can see a white band around the base of a now lifeless 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.

This can also be readily viewed in Yellowstone.

As one walks through these more active geo-thermal areas within Yellowstone National Park, one is admonished to stay on the wooden walkways that have been provided.

This is to ensure one's safety as well as to protect this fragile environment.

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

Great souvenir to have showing the effects of algae in Yellowstone. Your Christmas tree can be a place for memories of your travels...or wish list of places to see for that matter.

 

First 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 areas pictured here, there is much in the way of wilderness with mountains and valleys.

Hiking, camping, fishing, and / or 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 Yellowstone.

Learning about Mother Earth from this unique place on the planet can be interesting and fun.

The last photo shown above has scalloped edging around the deeply pigmented pool of water. These are formed 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 might be suspended in the water among other things.

Pigments within the microorganisms themselves also account for different coloration.

Hopefully these pictures of the effects of algae and bacteria in Yellowstone will entice you to come and take a look at this amazing color display for yourself someday. There is much more of Yellowstone to see! I'll be looking forward to your comments.

This is the same area from which most of my photos were taken..

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!

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… :)

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.

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.
