West Thumb Geyser Basin

West Thumb Geyser Basin is one of the smallest geyser basins in Yellowstone yet its location along the shore of Yellow-stone Lake ranks it as the most scenic. West Thumb derived its name from the thumb-like projection of Yellowstone Lake and the name was given by the 1870 Washburn Expedition. It was also known as Hot Spring Camp. West Thumb has less geyser activity than other basins. But West Thumb, for its size, has it all—hot springs, pools, mud pots, fumaroles and lake shore geysers.
