There are two "high routes" decribed on the internet (Dixon and Skurka), as well as several others. You need to state exactly which "Wind River High Route" you are intending to do. It is, so far, a high snowpack year in the Winds, so you will likely run into some steep snow, unlike last year. Personally, I would not do any of these thru-routes with someone I had never backpacked with before. Minimally, if you find someone on the internet, do a trail-run trip to be sure they are as qualified as they claim. Good Luck!
