The Sheldon - Hart Mountain National Wildlife Refuge is located north of the Black Rock Desert, near Nevada State Route 8A.

In 2010, this area was the furthest location from a McDonald's in the contiguous US[1].

Geology

The Lone Pine mining district is to the west of the area, straddling the California/Nevada border. The area consists of basalt lava flows[2].

A 1985 report[3] states that the Virgin Valley area has opals, and low-grade uranium deposits. Elsewhere, there are mercury deposits.

Calderas in the area are proposed as the initial impingement of the Yellowstone hotspot[4].

In 2014, a earthquake swarm[5] occurred in the region, probably associated with a caldera that is detectable via a gravity anomaly[3].
