It is a northwest–southeast trending range, about 20 miles (32 km) long and composed of volcanic rocks.

The central part of the range is the New Water Mountains Wilderness[2] with a lengthy east–west border on the northern Kofa National Wildlife Refuge of about 12 miles.

Three northerly routes access the mountain range; the central route accesses the Ramsey Mine and eventually the central dry wash on the north; other mines, such as the Republic Mine, are in these mountains, as well as some springs (Dripping Springs); also Brintley Well on a fourth westerly access route.

The closest community to the north side of the mountain range is Brenda, Arizona, east of Quartzsite.
