Where to Find Agate in New Mexico

New Mexico agate concentrates in the southern bootheel and along the volcanic belts of the southwest quadrant. The Baker Egg beds south of Deming yield small, brightly banded thundereggs in rhyolite, and the Black Range west of Truth or Consequences produces red-and-yellow plume agate from the old Sierra County diggings. The Apache Creek area in Catron County is known for moss agate and pseudomorph nodules in welded tuff. Up north, the Bingham fluorite-agate area in Socorro County yields a violet-and-purple agate associated with the local fluorite veins. Surface collecting is open on most BLM ground in these regions. The most productive ground is in Baker Egg thunderegg beds (Luna County), Black Range plume agate (Sierra County), Apache Creek moss agate (Catron County).

Casual hand collection of common rocks and minerals like agate is allowed on most BLM and U.S. Forest Service land in New Mexico, with daily and annual limits set by the local field office. National parks, most state parks, and tribal land are off-limits. Always confirm rules before a trip.

Baker Egg thunderegg beds (Luna County) is the standout. Other strong ground includes Black Range plume agate (Sierra County), Apache Creek moss agate (Catron County).
