About Trilobite Wilderness
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. Wildlife is also typical for the Mojave Desert. 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. The wilderness is located in the central portion of the sector and consists of 37,3
