Ledge Geyser


Ledge is the second largest geyser in the Norris Geyser Basin, capable of shooting water 125 feet into the air. Because it erupts at an angle, however, the water will sometimes reach the ground 220 feet away. It has at times in the past erupted at regular intervals of 14 hours. The geyser became inactive between 1979 and late 1993. It erupted on a fairly regular cycle of every four to six days in 1994 and 1995. The most recent eruption was in the Fall, 2006.
