South side of Millcreek Canyon (north facing). Generally shady and always secluded! The rock is typical lower canyon Millcreek limestone...ie, not all that much to write home about.
The rock quality does have the capability to excite the lower GI Tract, however, and one could suffer from tenesmus.
Getting There
The Log is a little tower visible from the road right at the mouth of the canyon before one even passes the ranger collecting entrance fees at the ticket booth.
So you don't even need to bring along your tickets.
