Planning my first trip out west 3 Rd week of June. Rode in Smokie Mountain ranges but not the Sierras & Rockies of Colorado. Be traveling thru Wolf Creek pass, Red mountain pass & Monarch pass & a couple others along that route I can't remember. Are snow chances at this time normal? Guessing temps probably in 30s at 9,000 - 11,0000 ft. Any tips beside warm clothing?
