The earthquake fault in California's Mammoth Lakes area is actually an earthquake fissure because the vertical rocks on both sides have barely moved, so technically it’s not a true fault. While the exact age of the fissure is unknown, some of the trees growing around it are over 160 years old. The sides are still jagged and uneroded, suggesting it’s quite young in geologic time. Scientists believe it was formed in the last 200 to 600 years by tectonic stresses in the earth’s crust.
