I wandered around Dry Falls (central Washington) with my 8x10 in some fairly hot weather...over 105F, but don't know exactly how much over. Started early in the morning and did the only uphill part early in the day.
When the weather is that hot, one does not have to worry too much about the rattlesnakes -- or other people. But I finished up by 1 or 2 pm as not to over-due it. I headed into town for lunch in a cool (temperature-wise) cafe, did some exploration by car up towards Grand Coulee Dam, and returned near sunset.
The first image is of some branches of a dead tree with the falls behind (dry, of course). The second was up on Umatilla Rock, the highest point, elevation-wise, of my day.
