West Face of Mammoth Rock, standing below "Bridge of Sighs" . "Proboscis" to the left. There is a large, triangular cave on the wall. "Proboscis" skirts the left edge and "Bridge" skirts the right edge.

Start of "Proboscis" on Mammoth rock. 510+

The second pitch of "Proboscis" is exposed and mentally challenging. Although this section is 5.9, the overall rating is easily 5.10d, not 10c as the Bay Area guide-book indicates.

The "Africanized" Start of "Bridge of Sighs" follows the right angling overhang to join the route. Rated 5.11-. The remainder of the route is 5.10+. Although the second pitch climbs the right edge of a triangular cave and then angles up and right on ramps to a small headwall, a spectacular variation is to link up with "Proboscis" by climbing up and slightly left after the cave.
