The last time I went to Crater lake I hiked down to the boat launch and swam in the lake on a nice hot day.
I've been there in the summer when the lodge was still covered with snow and had a sign asking visitors
to stay off the roof!
Another time it was really smokey from fires, or cold and scary windy on the ridge tops.
I don't know, somehow volcanos like Crater Lake and Mt. Shasta have just gotten into my blood.
