The Wind River High Route is 97 miles long, 65 percent off-trail, and follows the alpine crest of Wyoming’s Wind River Range, usually hovering between 10,000 and 12,000 feet. Its termini are Bruce Bridge and Trail Lakes, both on the eastern side of the range, connected by long cross-country segments with short bits of trail. Modelled after the design of the Sierra High Route, it stays as high as possible while traversing no technical terrain (Class 5), crosses mostly non-crevassed glaciers, and offers plenty of boulder-hopping. It is perfectly bookended by the southern and northernmost 13ers in the range, Wind River Peak and Downs Mountain.
The Dixon/Wilson variation is a different route but was given the same name. It is 80 miles long and 45 percent off-trail, and terminates at Big Sandy in the south and Green River Lakes in the north, on the west side. It may be the more popular of the two, due to its shorter length and being easier. More info: http://www.adventurealan.com/wind-river-high-route-guide/
