I was up there in '81 and remember a couple hippies laying down on the ground smoking pot on the summit and looking up at a cloud formation that was descending down on them and one of them saying to the other something to the effect, "Dude, we're being descended upon".
What was funny is that there really was a cloud formation descending on them, I saw it also. It was kind of strange, because it was a sunny, cloudless day (I got the worst sunburn in my life on that day...another story...).
