"The Mountain Makes It's Own Weather."
This is true of even ghost mountains like Mt. Mazama. Now Mazama collapsed a good five thousand feet awhile back in an eruption that forced people up to seventy miles away to dive into Klamath Lake and today it is still a little temperamental.
For instance while I worked the rim my hands were freezing in their insulated gloves, my back was hot under only two thin layers, and it went from sunny and June to a quarter inch of hail on the ground in about five minutes.
At least it is never boring.
