Prepare for snow up high by sept 1, bring warm clothing. Sounds like a blast. Nice pics! And good luck!
Water can be hard to find up in that area, I try to drink and fill often if I don’t know the area. Rams can sometimes be found near the highway but good to get at least 5km back. If you find a horse trail and it crosses the creek, cross the creek! Sun at your back and wind in your face. Glass, glass, glass.
