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.
