Here's some interesting stats for a few mountain-tops in the USA. These are the average morning lows and afternoon highs for each location. Has anyone ever seen a weather station on Mt. Rainier? The data for Rainier is from the NPS. I assume it could be an estimate rather than a weather station?
Also, I know temperatures are taken daily from sometime in April through mid-July (the normal climbing season) at the high ranger camp on the West Rib of Denali. Anyone know where to access the data? Minimum gage thermometers have plunged to -95 on the summit of Denali, but since there isn't an official station up there, this figure is always excluded when extreme record lows for Alaska are listed in the almanacs.
Mt.Washington, New Hampshire (6288 feet)
Mt. Lovenia, Utah (13,219 feet)
Mt. Rainier, Washington (14,410 feet)
Mt. Lovenia is fairly close to the Colorado Rockies, and I would assume temps on the 14'ers might be similar, but a little colder. I assume the 14'ers are a bit drier as well. Notice that Mt. Lovenia and Mt. Washington have very similar daytime temps, but Mt. Lovenia is colder at night. Both locations probably recieve similar snowfall and precip values, and both are either too warm in summer or too dry to form glaciers. Mt Rainier has similar temps in winter to the other locations, but is much colder in summer. It is also much wetter and is heavily glaciated.

I'm not really just trying to dig up old data -- I can't seem to get any of the current sites to actually load in my browser!
