Jobsite is a quartzite/tillite area located on the north side of Rock Canyon, just east of the mouth of the gully above the water tank (Trilogy Gully). The lighter colored quartzite sits above a layer of fairly dark brown Mineral Fork Tillite.
There are several sections: The left, moderate side of the south-facing wall is on sharp, irregular rock.
The middle section of the south-facing wall has a large, sharp-edged roof sloping down from left to right.
The right side of the south wall has a large, irregular roof above a substantial thickness of tillite.
Finally, there is an upper tier that can be accessed via several of the routes on the left side of the south-facing wall.
Most of the route names come from the route developers' recollections of their "worst jobs."
Getting There
To get to the left side routes: 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 the crag.
To get to the middle and right side: Start as above then continue past the water tank on the dirt road. Head up the trail on the slope under the right side (towards the mine entrance). Head for the roof area just left of the trail.
