August came to be the summer month that nothing happened in in part because cause that’s also (coincidentally enough) when the winter’s “ice” would run out. They’d saw big blocks of ice in winter and ship it out to, well, everywhere. They’d use straw and cork-lined railroad cars as insulators. Worked fairly good until around August.
MOUNTIANS can get cold at night, as I checked Denver is sitting at about 80°F, Vail is 59°, less than 80 miles, (as the crow flies), away.
I'm not quite sure of your point here. Yes, I'm well aware of mountains and temperatures. I could talk about how at the time you typed your post it was about 80 degrees where I am and only about 20 miles away it was about 60. Of course, I could also point out that tomorrow afternoon that, where I am, it is supposed to be 94 degrees and it is supposed to be 67 just 20 miles away. It is amazing the difference a few thousand feet of elevation can make (both in my case, and the case of Denver compared to Vail).
The issue is, Lake Powell is at roughly 3500 feet across the entire lake (as I mentioned earlier), and is not in the mountains (again, it is on the Colorado Plateau). At the same time, that was somewhat my point. Servus kept talking about the heat and my point was, compared to Lake Mead, there is no "extreme" heat; pretty much all the places I've lived in the US have had high temperatures that averaged at least as high (or higher) than what Lake Powell does. Now, the fact that it the area around Lake Powell is something like 3500-4000 feet, as well as being arid, does mean it cools off at night (unlike those places I've lived, which tended to be humid).
In fact, it is kind of interesting that one of the big complaints about Glen Canyon Dam, at least as far as how it affects the Colorado River and the Grand Canyon, is that the water is too cold. Previously, before the dam, after spring runoff ended, the water in the Colorado River (which could often be relatively shallow in the summer) would heat up to roughly 80 degrees. With Lake Powell there, the lake keeps the water cooler, so that Colorado River water just below the dam is typically under 50 degrees (and also much clearer, since the silt that previously in the river is now stopped by Glen Canyon Dam). It is interesting how much that has
affected nature below the dam and through the Grand Canyon.
