  Crack - Lower Geyser Basin
Feature Type: Geyser
Geyser/Spring Type:

Lower Geyser Basin
White Dome Group

Crack Geyser is located southeast of Gemini Geyser on the same sinter mound. The 1959 Hebgen Lake Earthquake created a "crack" about 8 feet long in sinter. The southern end of the crack is a few feet east of Pebble Geyser.

Crack has been infrequently active over its history. It was first active as a fumarole following the 1959 earthquake, then began erupting in 1960. The eruptive activity lasted only a few months. It was active again in 1969, 1983, 1987-1988, and a few days in each of 2006 and 2007.
