Thanks to Steven Wagoner for adding this loop. It's my favorite run in the area. Started and finished at the gate at the start of the North Ridge Trail and ran around the picnic table a the top of the mountain.
Deviated from Steven's track in two places: at the top to avoid a restoration area and at the base of the East Ridge Trail to limit a detour to Connor's camp.
