North Yolla Bolly Trails

The North Yolla Bolly trail network. The main trail departs from the Stuart's Gap trailhead and passes through Pettijon Basin en route to the ridge connecting North Yolla Bolly and Black Rock Mountain. Trails to both mountains branch off of the main trail. Side trails through the basin lead to North Yolla Bolly Lake and Black Rock Lake. The dashed lines indicate routes to the summit of Black Rock Mountain. While the dry gulch route as been ascended, the route departing from the lake has not been completed as of this posting.
