Artists Paint Pots

Yellowstone National Park, Wyoming, USA

Situated just three miles south of the Norris Geyser Basin is the generally less active Gibbon Geyser Basin. It is here where several collections of thermal features are found, of which Artists Paint Pots are the most popular.

The Paint Pots are a group of over 50 springs, geysers, vents and active mud pots. These exhibit a wild array and shades of blue, grey and brown colors with varying textures. Their behavior changes during the year depending on the amount of subterranean water.

Geyser Burnt Trees

Yellowstone National Park, Wyoming, USA

Bleached remains of trees close to one of Yellowstone famous geysers. It’s not the pine wood beetle that has killed these specimens, but the toxic and ever-present hot conditions from the daily eruptions.

New pine samplings will grow nearby, however, as they age their fate will be the same. It is a saddened beauty that beholds this land.

Grand Prismatic Microbial Mat

Yellowstone National Park, Wyoming, USA

The Grand Prismatic Spring microbial mat, which is a multi-layered sheet of microorganisms, surrounds the hot springs showing off its many vivid colors. The intrinsic blue center of the pool (upper right of the photo) is completely sterile due to the extreme heat. The hot spring discharges an estimated 560 US gallons (2,100 liters) of 160 °F (70 °C) water per minute.

Grand Prismatic Spring Overlook

Yellowstone National Park, Wyoming, USA

Hiking then climbing to an overlook behind the colorful Grand Prismatic Spring one is rewarded with an extraordinary view of this special place. The blue center of the pool is sterile due to the extreme heat produced by the hot spring, while the orange around the edges are microbial mats.

Isa Lake Yellowstone

Yellowstone National Park, Wyoming, USA

In midsummer water lillies cover Isa Lake in Yellowstone National Park.

The lake is situated right on the Continental Divide at Craig Pass between Old Faithful and West Thumb. Geographers call it a drainage divide or boundary between two watersheds, one which flows to the Atlantic Ocean, the other to the Pacific Ocean.

Mammoth Hot Springs, Yellowstone

Yellowstone National Park, Wyoming, USA

View of part of the Upper Terraces showing the calcium carbonate deposits created after the hot spring water has cooled. Getting about the complex is easy as boardwalks cover nearly 1.75 miles around the Upper and Lower Terraces.

Mammoth Hot Springs are located just south of the North Entrance to Yellowstone, near the town of Gardiner in Montana.

Mammoth Springs, Yellowstone

Yellowstone National Park, Wyoming, USA

Mammoth Hot Springs is a complex of hot springs which has been created over thousands of years in Yellowstone National Park. It is on a hill of travertine – limestone deposited by mineral springs where calcium carbonate is formed as the hot water cools and is then deposited.

This is the top of Palette Spring Terraces which are part of the Upper Terraces, which also include: Opal Terrace, Liberty Cap, Minerva Terrace, Cleopatra Terrace, Jupiter Terrace, Main Terrace and Canary Spring.

Microbial Mat at Grand Prismatic Spring

Yellowstone National Park, Wyoming, USA

Grand Prismatic Spring is the largest hot spring in the US and the third largest in the world. The vivid colors around the edges of the mineral-rich water in the spring are the result of microbial mats, while the center of the pool is sterile due to extreme heat.

The amount of color in the microbial mats depends on the ratio of chlorophyll to carotenoids (organic pigments produced by plants and algae), and also on the temperature gradient in the runoff.  The mats tend to be mainly orange and red in the summer, and usually dark green in the winter.

Off the Trail

Yellowstone National Park, Wyoming, USA

A flash of color while walking from Artists Point on Uncle Tom's Trail to the Lower Falls in Yellowstone. This steep trail takes you from the top of Yellowstone's Grand Canyon down to the base of the 308-foot-high Lower Falls.

The walk down 500 feet is fairly strenuous, however, in 1905 Uncle Tom lowered you by rope!

Reflections of Pride

Yellowstone National Park, Wyoming, USA

A last stand for the dead trees sitting in shallow water at the Firehole Lake Drive in Yellowstone National Park. They have been killed by a shift in geyser activity.

As the trees mature their root structures search deeper only to be consumed by excess heat and toxicity created by the thermal activity.

Tapestry of Microbes

Yellowstone National Park, Wyoming, USA

Grand Prismatic Spring in Yellowstone exudes such vivid colors around the edges of the mineral-rich water in the spring. These are the result of microbial mats which tend to be mainly orange and red in the summer, and usually dark green in the winter. The center of the pool is sterile due to extreme heat.

Travertine at Mammoth Hot Springs

Yellowstone National Park, Wyoming, USA

Travertine is a form of limestone deposited by mineral springs, especially hot springs. It is formed by a process of rapid precipitation of calcium carbonate at the mouth of the hot spring.

The classic fibrous appearance of the travertine at Mammoth Hot Springs with its array of white, tan, rusty and cream-colors can be seen in this image.
