AC/DC is located on the right (east) side of the gully below Trilogy Buttress. There are a number of bolted routes in two tiers.
On the upper, left side there are four bolted routes in and around two prominent black streaks in the quartzite. On the lower, right side there are four bolted routes on the lower tier. One of these routes continues for two additional pitches on the upper tier and there is project as well.
Although the rock is surprisingly good for its location helmets are still recommended because not all loose material has yet been knocked off.
Getting There
From the parking lot stay left on the road, cross the streambed, and walk to the water tank on the north side of the canyon. Just past the water tank head up a trail to the right of the talus.
Keep heading uphill, passing through some scrub oak until you reach the base of a light-colored crag (The Jobsite) at the bottom, east corner of the gully.
Continue up the gully, staying right of the talus on a faint trail (you can completely avoid the talus). The routes are 200 feet or so up the gully from The Jobsite.
A very enjoyable, two-pitch climb.P1 (60', 5.7) A fun, interesting pitch on good feet and positive handholds through very good quality rock. Start on a small ledge and climb low-angled terrain through the first bolt to a short headwall. A fun move or two to get past the steep bit, clip a bolt, and then bear left.Climb a steeper section through three bolts on good holds, and then continue on somewhat lowered angled rock to the anchors.P2...[more]
