I can' t help much with elk info in that area, but I hunt first rifle season in unit 1. This is a few weeks later than archery and we' ve had everything from T-shirt weather to froze rain to snow up to our butts, sometime in the same week. Chances are your weather will be warm durnig the day and cool at night. The weather in the Rockies can be pretty variable so pack you clothes accordingly. Lighter clothes that I can layer always work for me.

I' ll get this one for you Beaverjack........Wear Wool!!!!!
