Kilbourne Hole — Rockhounding in Doña Ana County, New Mexico

Kilbourne Hole is a BLM-managed maar crater and National Natural Landmark where volcanic bombs can contain bright olivine-rich interiors. BLM, Recreation.gov, and New Mexico Bureau of Geology rockhound material all point to its mantle xenolith and peridot appeal, a very different target from the state's agate and jasper localities. Reported finds include augite, peridot. Below: coordinates, access notes, nearby spots, and trip-planning links.
