Mogollon Mountains

They extend roughly north–south for about 30 mi (48 km), and form part of the divide between the San Francisco and Gila Rivers.

The crest of the range lies about 15 mi (24 km) east of U.S. Route 180, which traverses parallel to a section of the San Francisco River.

The Mogollon Mountains were formed between forty and twenty-five million years ago as part of the Datil-Mogollon Volcanic Plateau.

[2] The Mogollon Mountains are named for Juan Ignacio Flores Mogollón, governor of Spanish colonial Nuevo Leon from 1712 to 1715, in the Viceroyalty of New Spain.

Mining occurred in the area beginning in the 1890s and continuing for some decades when the natural grizzly bear population was destroyed.
