At 11:37 p.m., local time, August 17, 1959, the earth shook. Thus began the Hebgen Lake Earthquake, registering 7.5 on the Richter scale. Less than a minute long, it sent a 100 MPH, 80 million-ton landslide barreling down one mountainside and 400 feet up another. The quake blocked the Madison River, creating 190-foot-deep Earthquake Lake, dropping the bottom of adjacent Hebgen Lake 20 feet, and burying a campground under 230 feet of rock. Twenty-eight campers died, including 19 never found, and 250 were rescued the next day. In Yellowstone National Park, the quake slowed the Old Faithful eruption cycle by four minutes and caused dozens of thermal features to spew mud and water.
