Description

This large boulder is host to one excellent sport route, 'Mentor'.

Getting There

Take the Fern Canyon trail, past the Superfresh Block, to a large boulder that sits along the right side of the trail. It is located a few hundred yards below the saddle at the top of the Nebel Horn Ridge area.

It is easily identified by a line of bolts that ascends through huecos on the steep south face.
