Geology behind New Mexico rockhounding

Southwest New Mexico's Tertiary volcanic field produces many of the state's common targets, including thundereggs, agate, jasper, perlite, and Apache tears. The Rio Grande Rift exposes Precambrian and Paleozoic mineralization through central New Mexico. The San Juan Basin in the northwest has petrified wood and Cretaceous invertebrates. The Pecos and Sangre de Cristo ranges add pegmatite minerals.

Best regions to focus your search

Southwest (Rockhound State Park, Deming, Bisbee Hills)

Rockhound State Park (where the state actively encourages visitors to take a small amount of material), Spring Canyon, the Florida Mountains, and Apache tears at Round Mountain. The state's main collecting hub.

Central New Mexico (Magdalena, Socorro, Mockingbird Gap)

Smoky quartz, fluorite, mine-dump barite, and selenite. The Magdalena and Kelly mining districts produce a long list of secondary minerals.

Northwest (San Juan Basin, Bisti)

Petrified wood and Cretaceous invertebrate fossils on BLM. The Bisti/De-Na-Zin Wilderness is closed to collecting; surrounding BLM is open under the standard rule.

Best season

October through April for the southwest deserts; summers are hot. The Sangre de Cristo and Jemez highlands are easier from May through October.

What to bring

Water, sun protection, and a rake for surface-picking thundereggs and Apache tears in the southwest. The Florida Mountains are steep and in snake country, so wear sturdy boots.

Local collecting history

Rockhound State Park near Deming, established in 1965, was the first state park in the U.S. created specifically for rockhounding. New Mexico designated turquoise as its state gem in 1967; the historic Cerrillos turquoise mines south of Santa Fe are mostly closed but a few still offer occasional tours.
