The United States Congress designated the Cache Creek Wilderness (map
) in 2006 and it now has a total of 27,296 acres
All of this wilderness is located in California
and is managed by the Bureau of Land Management.
The Cache Creek Wilderness is centered on a 17-mile stretch of Cache Creek flowing from Clear Lake in eastern Lake County. The prominent feature within the wilderness is Cache Creek, which runs east towards the Capay Valley and the Sacramento River while forming a steep-sided canyon through most of the area. The steep canyon walls occasionally open to broad, grassy meadows with scattered valley oaks, such as Baton Flat, Wilson Valley, and Kennedy Flats. Numerous steep tributaries also feed into Cache Creek within the wilderness including Dry Creek, Rocky Creek, Trout Creek, and Crack Canyon. Outside the river canyon, the majority of the wilderness is dominated by rugged chaparral-covered hills. Elevations within the wilderness area range from 750 feet on Cache Creek at the eastern boundary to 3,196 feet at Brush Sky High.
