Prehistoric and historic resource inventory was carried out within the Cache Creek drainage as part of a Cultural Resources Program initiated by the Ukiah District of the Bureau of Land Management (BLM). From late 1986 through June of 1987, volunteers and BLM staff recorded, re-recorded, or confirmed 34 Native American sites, 5 with historic materials. Seven historic sites were also identified. A long-term program for managing these cultural resources has been implemented. The baseline inventory is being used to track resources through site and photo-monitoring. The monitoring program consists of 1) describing site conditions; 2) placing photo-points and erosion stakes for long-term site assessment; 3) establishing a management use (MU) classification for each site; and 4) disseminating the information.
