Saturday we spent the day trout fishing in the Clarks Fork Canyon north of Cody and it was about 95 degrees at around 5500 feet. Sunday evening we were coming out of the east gate of Yellowstone in a light snow. The next morning the Beartooth, Pryor, and Bighorn Mountains all had snow on the roof. Went up to the Medicine Wheel in the Bighorns on Monday at around 9600 feet and froze my ass off at 30 degrees, 20mph winds, and a few inches of snow on the ground. Yikes, winters on the way.
