Ellis, you know, I never though of that, the seasonal snowfall on the Big Island doesn't appear to be diminishing, at least it hasn't been reported as receiving less snow than normal. My son graduated from U H Hilo (Home of the Vulcans!) and I've got photos of him on my office wall up on Kilauea snowboarding. Kili's closer to the Equator, but awfully high as well, something over 19,000 at the peak. You'd think it wouldn't get that much new snow. The Hawaii mountains are something around 14,000 I believe.
