Why Visit Wilderness?

While wilderness can be appreciated from afar—through online content, television, or books—nothing compares to experiencing it firsthand. Activities like camping, hiking, or hunting allow you to fully enjoy the recreational, ecological, spiritual, and health benefits that wilderness areas offer. These areas provide “outstanding opportunities for solitude or a primitive and unconfined type of recreation,” chances to observe wildlife, moments to renew and refresh, and the physical benefits of outdoor exercise. In many wilderness areas, you can even bring your well-behaved dog.

The Trilobite Wilderness covers the Marble Mountains, a narrow volcanic range extending 12 miles in a northwest-southwest direction.

Alternating dark brown and light brown striations have been tilted by geologic processes and give a marbled appearance to the range. Through the center, several yellowish sandstone peaks with long talus slopes are prominent.

Trending eastward from the mountain range, the Wilderness includes low rolling hills and sloping bajadas.

Vegetation is characteristic of the lower Mojave Desert, consisting of creosote bush scrub and desert wash scrub.

Wildlife is also typical for the Mojave Desert; including coyote, black-tailed jackrabbits, ground squirrels, kangaroo rats, quail, roadrunners, red tail hawks, prairie falcons, rattlesnakes, and several species of lizards. The area does have a very stable permanent population of bighorn sheep last estimated at around 150, and the eastern portion of the Wilderness provides critical habitat for the threatened desert tortoise.

Location

Trilobite Wilderness is located in San Bernardino County, California approximately 60 miles west of Needles, CA in between I-40 and historic Route 66. Maps of the area can be obtained from the Bureau of Land Management Field Office in Needles, California.

Maps

Digital and paper maps are critical tools for wilderness visitors. Online maps can help you plan and prepare for your visit ahead of time. You can also carry digital maps with you on your GPS unit or other handheld GPS device. Having a paper map with you in the backcountry, as well as solid orienteering skills, however, ensures that you can still route-find in the event that your electronic device fails.
