Summary
This polygon shapefile depicts lithologic contact, fault contact, and watershed boundary as line attributes for the Noyo River Watershed, which lies within the Coast Ranges physiographic province of California. The area is mountainous, with elevations ranging from sea level in the coastal area of the watershed to approximately 2,850 feet in the eastern headwaters portion of the watershed. Geologic units include undivided Quaternary sedimentary rocks, beach and dune sand, estuarine deposits, marine terrace deposits, older dune sands, Franciscan melange, Coastal Belt Franciscan Complex, and Coastal Belt Franciscan Complex, greenstone. The majority of the watershed is heavily forested; portions of the extreme western and southeastern portions of the watershed are grass covered. This map set was compiled from multiple sources including published maps and reports, unpublished mapping by the U.S. Geological Survey, aerial photograph mapping, and reconnaissance geologic mapping. Results of Noyo River Watershed Landslide Mapping Project, including geologic and geomorphic features (landslide) maps and landslide potential maps. The maps/data are useful in preparation of Timber Harvesting Plans, and for use by land managers for identifying areas of potentially unstable ground. The maps/data serve as a guide to potential problem areas where more site-specific review is required. California Division of Mines and Geology. (2001).
