Hatch is a useful southern New Mexico agate and jasper area because it represents the broad volcanic terrain around the Caballo and Hatch country, not a single pay-to-dig pit. BLM rules provide the public-land collecting framework, while New Mexico Bureau of Geology and established rockhounding guides list the area for agate, chalcedony, jasper, and quartz. Reported finds include agate, chalcedony, jasper, quartz. Below: coordinates, access notes, nearby spots, and trip-planning links.
