- The Cache Creek Wilderness is a 27,245-acre (11,026 ha) wilderness area located in Lake County, California. The wilderness was added to the National Wilderness Preservation System when the United States Congress passed the Northern California Coastal Wild Heritage Wilderness Act in 2006 (Public Law 109-362). In July 2015, the area became part of Berryessa Snow Mountain National Monument. The Department of the Interior's Bureau of Land Management (BLM) is the agency in charge. The centerpiece of the wilderness is Cache Creek, a tributary of the Sacramento River (in high rainfall years). Cache Creek is one of two tributaries (Putah Creek is the other) that are the most southerly of the significant east-flowing Coast Range drainages in the Sacramento River hydrologic basin and provides important riparian and fish habitat. More than 30 miles (48 km) of Cache Creek is designated a California Wild and Scenic River. The wilderness area is within the larger Cache Creek Natural Area of more than 70,000 acres (280 km2), and has a wide variety of plant and animal life, including a year-round population of bald eagles and California's second-largest herd of rare endemic tule elk. Highest elevation point is Brushy Sky High at 3,176 feet (968 m). A topography of steep, rounded hills, open meadows, cliffs and stream canyons support vegetation of manzanita, interior live oak, scrub oak, deerbrush, toyon, birchleaf mahogany, and gray pine as well as serpentine and chemise chaparral. Streamside vegetation include trees of willow, alder, and grasses such as sedge and bulrush.Rare native plants observed in the Cache Creek area include Hall's harmonia, an aromatic annual wildflower, and the adobe lily which are listed by the California Native Plant Society as category 1B-meaning the plant meets all criteria of section 2062 of the California Endangered Species Act. There are significant archaeological sites documented, including the remains of a large Hill Patwin village occupied around 11,000 years ago. The Cache Creek area has been and continues to be a popular recreation site for a variety of activities including white-water rafting (called the "wilderness run"), bird watching, hiking, backpacking, fishing and nature photography. Adjacent to the wilderness is the 2,330-acre (9.4 km2) Cache Creek Wildlife Area that is managed by the California Department of Fish and Game, Yolo County Parks and Bureau of Land Management. Wildlife species include black-tailed deer, tule elk, wild turkey, quail, rabbit, gray squirrel, dove, pigeon, black bear, raccoon and mountain lion. (en)
