This bisection point is the approximate center of the mostly northwest by southeast trending range. The northwest section contains a steep escarpment on the northeast with the Verde Valley, the escarpment being the cause of the fault-block that created the available mining district at Jerome, Arizona, which is a major historical and tourist landmark of the Black Hills range.
This Black Hills range is also the first major fault-blocked range west of the Mogollon Rim on the southwest of the Colorado Plateau of the states of Arizona, Utah, Colorado, and New Mexico. The range is at the northwest-center of the Arizona transition zone which extends diagonally across central Arizona. Another range, the Black Hills (Greenlee County) is found in eastern Arizona on the Gila River.
