The Galena King mine is a historic hard rock mine located in Bernalillo county, in central New Mexico. It was actively mined from 1908 to the mid 1920s. The area became part of the New Mexico Proving Ground (current day Kirtland Air Force Base) during WWII to test proximity fuses. The mine suffered significant damage from illegal mineral collectors from the 1960s to present day. A group of volunteers called “Friends of Galena King” formed in 2014 to protect, preserve, and promote the mine so future generations can continue to appreciate its historic and geological significance.
