Throne Rock is the name given to a collection of routes that ascend the large boulders on the right side of the main Echo Canyon area. There are two very good routes in the area Orient Express (5.9) and Jack Knife (5.5). The first boulder contains the Practice Slab, an easy top rope face. There are three routes on the boulder behind the Practice Slab (including Orient Express), while the large boulder leaning against the wall at the top of the purple climbers trail contains Jack Knife.
