Mount St Helens erupted on 18 May 1980 with an blast estimated to have been 500 times as powerful as that caused by the atomic bomb dropped on Hiroshima in WWII. 57 people were killed, and 65,000 hectares (or 160,000 acres) of forest obliterated. The lateral blast stripped trees from mountain slopes within ten kilometres of the volcano and levelled nearly all vegetation for as far as 18 km away. 250 homes, 47 bridges, 24 km of railways and 300 km of highway were destroyed. The northern face of the volcano was engulfed in a massive rockslide and its summit reduced from 2,950 m to 2,550m, completely altering the landscape of the mountain.

It wiped out most, if not all, of the forests in the park. It also killed a bunch of people and flooded some of the rivers with ash.
