Gnil:

What is the temperature in the day ? at night ? And what about water temperature ? can you swim in it ?

in the hole, or jackson valley, it was really hot 84-90 F that week, on the river you need a shirt its in the 50's or 60's it creates its own weather.  the river is cold but dips feel good.  During the storm that produced the rainbows, it feel to 50 F, and we had a fire in the fireplace....   winter alwaysIMG_1184.JPG lurks in Wyoming.

when you're up at 10,000 feet like this on the Granite Highline Trail, its 70's.  i never wore a shirt  hiking in the 8,000-11,000 elevation range. [but watched the weather carefully]
