Though the attraction has been labeled an earthquake fault, there is uncertainty surrounding the fissure’s formation. While it was once believed to be a fault created by a single quake, geologists now believe it is actually a system of fractures created from several quakes, dating back approximately 550 – 600 years to the eruption of the Inyo Craters and Inyo Domes.
