Remembering the 1959 Hebgen Lake Earthquake that Claimed 28 Lives.

Earthquake Lake Visitor Center of Custer Gallatin National Forest, will recognize the event anniversary on Friday, August 16th, through Sunday, August 18th.

One late summer night, thousands awoke to a horrific nightmare: an enormous force rattling the ground beneath them. At 11:37 p.m. on Aug. 17, 1959, the 7.5-magnitude Hebgen Lake Earthquake hit southwest Montana. It was the second-largest recorded earthquake in the continental United States in the 20th century and is still among the largest recorded in the United States. The quake’s effects are still observed today.
