The 1959 Madison Slide, Part 2: Recovery and remediation - Caldera Chronicles
USGS Caldera Chronicles The 1959 Madison Slide, Part 2: Recovery and remediation Y ellowstone Caldera Chronicles is a w eekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Mike Stickney, Director of the Earthquake Studies Office at the Montana Bureau of Mines and Geology. The August 17, 1959, M7.3 Hebgen Lake earthquake caused incredible devastation throughout the greater Yellowstone region, and one of the most consequential impacts was the Madison Slide , which blocked the Madison River just west of Yellowstone National Park in Madison Canyon. Immediately after the slide occurred, the river began backing up behind the debris dam , flooding the canyon and forming what today is known as Earthquake Lake. Without intervention, this lake would have eventually overtopped the debris dam, potentially unleashing a flood that could have destroyed the town of Ennis, Montana, and other dow...
