For organizational purposes, the Solar Slab is divided into a lower and an upper tier. Obviously, a complete ascent to the very top would require linking a lower and upper route, or following one of the full-length routes described in the Upper Tier section. Most of routes in this section go from the ground to Terrace, a giant, multi-acre ledge about 500 feet up. There are two main ways to descend from the Terrace. Most common is to rappel the Solar Slab Gully. This can be done with a single rope. Alternatively, there are bolted rap anchors on Johnny Vegas; this route requires two ropes.
