Description

A nice slab feature that holds some history. In 1967, Greg Lowe lead and bolted a climb called 'Infinite'. Although there are several other routes here, including 'Memorial Day' 12a (originally called B2 by Greg Lowe in '67), it is this original route that attracted all of the early focus and attention.
