was designated under the Bureau of Land Management on this date in 2000.
[T]he California Coastal National Monument runs the entire length of the California coast (840-miles) between Oregon and Mexico, extends 12 nautical miles from the shoreline, and encompasses thousands of BLM administered islands, rocks, exposed reefs, and pinnacles above mean high tide.
Cooperatively managed with other federal, state, local government, universities, and private interests, the primary purpose of the Monument is to protect important biological and geological values. The islands, rocks, reefs, and pinnacles provide forage and breeding grounds for significant populations of birds and sea mammals.
