The Glass House is the other major cliff along the 158- sitting just south of Robbers Roost. This small cliff houses a handful of climbs in the 5.11 to 5.13 range and only gets morning sun, making it a good option for those hot summer days.
Starred routes here include Jet Stream, 5.13a and Throwin Stones, 5.12d.
Head north on the 158 from the 157, parking at the small turnout on the left that's about 200 yards before the large Robbers Roost parking area. (The parking area is the end of an old dirt road).
From the parking, follow the wash up for about 50 yards to a cairned trail on the left. Follow the trail uphill for a few minutes until you're just before a narrow gap, then look for a climbers trail cutting across the wash and heading up the hill on the other side. Follow this trail, cutting back sharply toward the road, then finally back up the hill to the cliff. Allow about 20 minutes for the approach. You'll arrive at the cliff at the base of Jet Stream, a 3 star 5.13a.
