Before Mt St Helens Erupted?

Answer

After the 1980 eruption, the north face of the tall symmetrical Mount St Helen collapsed in a massive rock debris avalanche. In a few moments, this slab of rock and ice slammed into Spirit Lake, crossed a ridge 1,300 feet high, and roared 14 miles down the Toutle River. Pressurised gases were also released to the air in form of thick ash.

The eruption of Mt. St. Helens disrupted the lives of thousands and changed more than 200 square miles of rich forest into a grey, lifeless landscape. The blast blew off the top of the mountain and killed approximately 57 people and showered towns as far as 250 miles away with volcanic ash.
Long before people arrived from the east, Mt. St. Helens was a sacred place for the local Indian tribes who had been witnesses to its long history of eruptive behavior and ancient legends caused them to give the mountain a wide berth.
