As you might imagine, Mauna Kea is on my "I have to do that sometime" list. Hawaii is the common tropical destination for us here in SoCal, and I have had 5 trips as an adult plus 2 as a child. Only one was to the Big Island, in April 1987. Yes I inquired, but no there was no snow. <BR> <BR>So there are two warnings: <BR> <BR>1) Snow coverage is wildly erratic. Make sure you know there's snow before you book. There are entire seasons when it's never skiable. <BR> <BR>2) You easterners need to take the altitude issue very seriously. As I found out driving Pikes Peak you will be in a lot of discomfort going from sea level to 13,000+ in less than 24 hours. <BR> <BR>By contrast I managed to climb Mt. Whitney (14,495) in 2 days after spending the previous 2 nights at Mammoth. So I would be tempted to drive up our local mountains and sleep at 7,000 the night before flying over there, and then do the skiing the first day there. <BR> <BR>An e-mail correspondent on the Solar Eclipse Mailing List told me there's a hut on Mauna Kea at 9,000 where the astronomers sleep. He strongly suggested trying to sleep there the night before skiing. And this is from someone who was up there for stargazing, not skiing. <BR> <BR>Another Whitney suggestion: take Diamox...and lots of water. Diamox stopped any altitude headaches, but it is a strong diuretic.
