Baldy Mountain lies on the northwestern border of the Scouting America's Philmont Scout Ranch.

Copper, gold, and silver were mined in the Baldy Mining District starting in 1866, and the top of Baldy Mountain was developed as the Mystic Lode copper mine. Other mines near Baldy Mountain were the Aztec, French Henry mine, Bull-of-the-Woods, Homestake, Black Horse, and Montezuma mines. Mine workings and prospects are still evident on the slopes of the mountain as well. There are about of mines in the whole mountain.
On the east side of Baldy Mountain, a small town grew up around the mining operations from 1868 to 1941. Baldy Town has since been incorporated as a staff camp at Philmont Scout Ranch.
