A top-100 ranked CO peak with high prominence and isolation, 13,821' Rio Grande Pyramid dominates the landscape.
From Thirtymile trailhead took Weminuche Trail #818 up to Weminuche Pass where a worn sign post indicates Skyline Trail heading west towards RGP (this trail may also be known as Highline, Opal Lake or Rincon la Vaca #714). This trail stays higher than and parallels the CDT down in the drainage below, and is the best approach to RGP. It hasn't had any recent maintenance so there are some downed trees and areas of willow to push through, but nothing too unpleasant. As RGP gets close and at the point where the Skyline turns south there is an obvious peakbagger trail that takes you up to a flat area below the peak and then up a steep scree/dirt slope to the base of the east ridge. From there its Class 2 talus straight up the ridge to the summit.
After summiting I continued south on the Skyline to connect with the CDT below The Window. The Skyline seems to fade out in some willow thickets about 250 yards before joining the CDT, but eventually you connect. East on the CDT down the drainage then back up to Weminuche Pass on Pine River #523 makes a nice lasso.
