Due to the fires in No Cal, I have chucked my plans to fly from my Wind River loop, flying to Reno for the TRT, but have instead decided to stay in Pinedale, resupply & head south on the CDT into CO. So my question: Where can I get the best detailed trail mileage (guide) for resupplying into Colorado? Guthooks?
Also, do I need a permit? If so what type?

Thanks Everyone
