I thought I was climbing Quarry Master....
Turns out, that route is 20 feet to the left. This route is the squeeze chimney directly beneath the Quarry. It's actually pretty good as far as chimneys go- until it pinches down halfway at a chockstone. Pull a sweet corkscrew maneuver to pass the chock and then join Quarry Master for the run out 5.6 gully to the quarry.
Best to approach from the top (Divide Road). The abandoned quarry sits on the west side of the wall. The guidebook mentions eye bolts at the bottom of the quarry, but I never found them. Sling a boulder and make a two rope rappel down to the base of the wall. The chimney is right there.
The chimney sections protects well with small to medium gear but bring some big bros if you got 'em.
