Figure 8.17 Ground Failure On August 17, 1959, an earthquake with a Richter magnitude of 7.3
shook southwestern Montana and a large area in adjacent states.

The fault scarp in this image was produced when the block in
the background moved up several meters compared to the one in
the foreground.

The earthquake triggered a
landslide (visible in the distance)
that blocked the Madison River in
Montana and created Earthquake
Lake (foreground). The slide
entombed approximately 26
people in a campground at the
very bottom.
