Mogollon Mountains, mountain range extending for 50 miles (80 km) east of the San Francisco River in southwestern New Mexico, U.S. Topped by Whitewater Baldy Peak (10,892 feet [3,320 metres]), the mountains are named for Don Juan Mogollon, Spanish governor (1712–15) of New Mexico province. Sometimes considered a segment of the southern Rockies, they are a headstream region for the Gila River and form part of the Gila National Forest and Wilderness Area. Mining and tourism are the main economic enterprises.
