Description

This is a solid slab that will be cooler than a majority of rocks in the canyon due to its shaded north-facing location. Top access is via a trail shortly west of the rock. There are a number of enticing trad crack routes, many moderate and excellent for beginning trad leaders. Cob has a number of classic climbs on it, put up in the '50s and '60s.

Getting There

About 6.1 miles up the canyon, on the south side of Boulder Canyon there's a pullout on the left side of the road beneath the rock. It's obvious. Crossing the river can be sketchy; we found it to be easiest via some rocks that are at the east edge of the pullout. Find the trail running to the right and up to the base of the rock.
Crossing the stream requires a Tyrolean in high water. There are a few of these along the stream, one of which is very close to Cob Rock.
