West Thumb Geyser Basin
Yellowstone Lake, Yellowstone National Park, WY
About
West Thumb Geyser Basin. This geyser basin is situated along the shore for a distance of two miles, extending back from it about five hundred yards and into the lake perhaps as many feet. There are several hundred springs here, varying in size from miniature fountains to pools or wells seventy-five feet in diameter and of great depth. Additionally, a small cluster of mud springs. Of particular note, the Abyss Pool offers an optical illusion that makes it look bottomless, and Fishing Cone is a offshore pool which was once popular as a spot to cook newly-caught fish by dipping them into this partially submerged hot spring (this stunt is no longer allowed).
