A (once) little-known road connected the sulfur mine south of San Felipe with Valle Chico and the canyons of the San Pedro Mártir mountain range. The road is in a pass named Cañada el Parral on topo maps. It is also called Azufre Wash by SCORE and called “Crazy Horse Canyon” by some locals. -- David Kier
