The Black Pearl was a group of prospects and adits worked in the mid-1900s producing manganese. Today little remains but the foundation and ruins of a small cabin guarded by two concrete gateposts.
The trail to the Black Pearl is relatively easy, crossing Coyote Wash and several more minor drainages. A cattle corral and windmill sit at Tiger Well. The trail can be run as a lollipop. The southern leg of the lollipop is seldom used, rougher than the rest of the trail, but scenic.
A few small campsites are scattered along the trail. Excellent campsites for any size group are scattered along the northern portion of Vulture Mine Road near the trailhead for Black Pearl.
