Upstate got nailed by Agnes in '72. That wasn't a picnic.
Caused about a dozen rock & mud slides on the mountains
They didn't kill anybody until 4 months later in winter when 5 numbskulls decided to ski down one of them on Wright Peak which triggered an avalanche killing one of them
Here's a picture of the slide I took from a safe distance of ~2 miles away the day before the skiers triggered it,
