Lunar Crater National Natural Landmark
From Wikipedia, the free encyclopedia

Lunar Crater National Natural Landmark recognizes the Lunar Crater volcanic field in Nye County, central Nevada, as a United States National Natural Landmark. It is located 70 miles (110 km) east-northeast of Tonopah[1] and was designated in 1973.
The volcanic field encompasses numerous volcanic craters and cinder cones, including a 400-acre (1.6 km2) crater that is thought to have been formed by several volcanic explosions and is one of the field's two maars.
