Park on the Mt. Lemmon Highway, approximately MP 5.8, at the very next drainage after the Molino Canyon Campground turnoff. There is a dirt pullout right before the drainage on the right side of the road. After about a hundred feet up the canyon (Harlan Canyon?) look for the biggest thumb of rock on the left slope , way back by the waterfall. Hike the drainage for about 20-30 minutes until you can cut up the steep slope to the left, just before the big waterfall. The climb starts in a left-facing corner that turns to a crack. This is about 30 feet up left from the oak tree at the lowest toe of the rock.
