The Lunar Crater volcanic field is a zone of vulcanism covering over 300 km2 at the southern end of the Pancake Range in the Great Basin Desert, Nevada. It contains numerous cinder cones and lava flows, fissures, and, most visibly, the 150 m deep Lunar Crater, a 1050 m wide and nearly circular maar (explosion crater) believed to have formed about 15,000 years ago.
Lunar Crater is one of Nevada's 6 National Natural Landmarks.
