Reef was a mining camp on Carr Canyon in the Huachuca Mountains, active from the 1880s into the early twentieth century for silver, gold, and tungsten. It took its name from the Carr Reef quartzite cliffs. The Coronado National Forest built a campground on the townsite in the late twentieth century. Remnants of the water system and other mining features remain around the sites.
