Located on the southwest side of Shoshone Lake, this geyser basin is reached only by hiking or by boat. One of the highest concentrations of geysers in the world is found here, with more than 80 in a 1,600 x 800 feet (488 x 244 m) area.

From 1926 to 1935, scientists Allen and Day conducted studies of the area and noted that the eastern side of the geyser basin is predominantly acidic, while the western side is almost entirely alkaline.
