Chambless Rock Collecting Area

Public area set aside for recreational collecting

Native material: you search the natural ground on site.

Season: October to April. Summer heat in the Mojave is dangerous.

BLM rock collecting area on the southern edge of the Trilobite Wilderness, in the Mojave along historic Route 66. Green epidote turns up in the washes, often with blades of shiny hematite; hematite and magnetite sit in reddish-brown iron deposits near old shafts; the side canyons hold tiny dark red to brown garnets, and an old quarry gives chunks of limestone and marble. The area lies inside Mojave Trails National Monument: the BLM still lists it as a rock collecting area, but the monument's management plan is being written and could change the rules, so check with the Needles Field Office before you go. The BLM also notes a gray limestone ridge full of fossils in a canyon farther east: only invertebrate fossils may be collected.

Access

From Needles, take I-40 west about 25 miles to the Mountain Springs Road exit, then the National Trails Highway (Route 66) west about 35 miles to BLM route NS328, just west of Chambless. Turn right and drive about 2 miles: the collecting area is on both sides of the route. The wilderness lies to the north: no vehicles there.

Technique

Hand tools only. Walk the washes for epidote and check the canyon gravels for small garnets. Stay out of old shafts and away from their edges. Personal collection only, in reasonable amounts.
