In many spots, it looks as though you would sink to who-knows-where if you stepped on the ground.  The paint pot areas are pretty fascinating.
The West Thumb Geyser Basin offers some beautiful views deep into the 
West Thumb Geyser Basin overlooks Yellowstone Lake, the largest lake at high elevation in North America.
One of the deeper hot springs in the park, Abyss Pool descends to 53 feet. It varies from turquoise blue to emerald green to various shades of brown. In 1883, a park visitor described it as "a great, pure, sparkling sapphire rippling with heat."
We loved visiting the park in the fall.  It was SO much better than fighting summer crowds and it was more beautiful!
As you walk among the basin's superheated waters, you wonder if the lake is warmer here than elsewhere. After all, the geyser basin pours an average of 3,100 gallons of hot water into the lake every day. But even here, the lake's average summer temperature is 45 degree Fahrenheit.
Different pool colors are the result of differing minerals in the soil.  This particular pool lacked whatever makes the water appear green or blue.
