Take a topo and area map from the refuge with you as it may become intensely foggy during the day especially if you go in the early side of the season (before May). Follow the left side of the rock forest past the archaeological site and past the perpendicular path that looks like a gap in the rock forest and walk downhill. It's the first big bolted wall and looks like it has a giant upside-down chevron carved into it and a small shallow cave to the right of it. It's a about a 15 minute approach from the refuge. Don't take the same path going back unless you love walking uphill in high altitude. Rather, walk into the rock forest gap and parallel to the incline.
