"Watching Old Faithful Geyser erupt is a Yellowstone National Park tradition. People from all over the world have journeyed here to watch this famous geyser. The park’s wildlife and scenery might be as well-known today, but it was the unique thermal features like Old Faithful Geyser that inspired the establishment of Yellowstone as the world’s first national park in 1872."

Hoof And Paw Prints On The Shallow Terraces Of Grand Prismatic Spring, Yellowstone National Park

white paw and hoof prints on the shallow terraces of Grand Prismatic Spring in Yellowstone National Park

If you take a winter snowcoach or snowmobile tour to Midway Basin and walk on the boardwalk around the edges of Grand Prismatic Spring, you'll notice paw and hoof prints on the shallow terraces of the hot spring. That white you see is not snow, but silica. The hot thermal waters hold silica in solution, and when the water cools, the silica precipitates out.
