Fence and rock rubble

Fence and rock rubble
As far as I could tell, a rock slide has wrecked the fence. There is a steep hillside above consisting of volcanic rock, which got there thanks to the series of massive blasts of Mt. Mazama, beginning about 5677 BC. The result was the beautiful Crater Lake in its collapsed caldera. Rock slides are common, but most do no harm in this area of sparse population. en.wikipedia.org/wiki/Mount_Mazama

Rock slides may be common (and do no harm) but how often does Mt. Mazama shake things up a bit?

"The volcano's compound edifice has been active relatively continuously since 420,000 years ago..." The most recent activity was a catastrophic blast 7,700 years ago, resulting in Crater Lake. It's technically an active volcano. Three puffs of dark grey smoke were seen in 1945, causing national news, but none since then. I couldn't find a straight answer about active vs. extinct, so I think the assumption is that it could blast away again. The whole chain of volcanoes in Calif, Ore and Washington are in that same category, I believe. (Definitely active: Mt. St. Helens in WA.)

P.S. I claim absolutely no expertise in interpreting the info on Wiki, Crater Lake Natn'l Park or US Geological websites!
