The Timbered Crater Roadless Area occupies three small segments of land totaling about 7 sq mi in Siskiyou and Shasta Counties, 75 mi northeast of Redding, California. A mineral survey indicated that the area has little or no promise for the occurrence of energy and mineral resources. Lava flows in the southern two segments of the roadless area contain large quantities of rubble that could be used in local construction projects. Further exploration in the area is unlikely due to the unfavorable geologic setting.
