Mount St. Helens

From USGS Volcanoes:

Do you recognize this Cascade Range volcano? Well on May 18 1980, the top 1,300 ft of the mountain was erupted away. That's right, this #TBT is an areal photograph of Mount St. Helens taken in 1979 by Rick Hoblitt. Mount Adams is visible along the left horizon.
