Mount St. Helens Erruption

Mount Hood

Mount St. Helens after erruption

Mount St. Helens is most famous for its catastrophic eruption on May 18, 1980, at 8:32am PDT which was the deadliest and most economically destructive volcanic event in the history of the United States. Fifty-seven people were killed; 250 homes, 47 bridges, 15 miles (24 km) of railways, and 185 miles (298 km) of highway were destroyed. The removal of the north side of the mountain reduced St. Helens' height by about 1,300 feet (400 m) and left a crater one to 2 miles (3.2 km) wide and 0.5 miles (800 m) deep, with its north end open in a huge breach.

Before 1980 Mt. St. Helens looked more like Hood. Wasn't the weather glorious for photography the last couple of days. We traveled across Washington on Highway 12 on Sunday. I took side trip up a viewpoint and got a photo into St. Helens' crater.
