San Mateo Rocks are uninhabited islands that lie approximately 0.5 mi (0.80 km) off the coast of California,[1] to the south of San Clemente, and just north of San Mateo Point, a minor headland that marks the border between Orange County and San Diego County.[2] The rocks rise about 3 ft (or about 1 m) above high tide.[3] In 2017 the San Mateo Rocks, a pinniped haul-out and scuba destination, became part of the California Coastal National Monument.[4][5]
The Rocks first appear in the documentary record of the area in 1889, when they were described in the Coast Pilot.[3] The sloop Victoria wrecked on the rocks in a storm in 1907.[6] In 1931 the United States Coast Guard reserved the location (along with several other Orange County Rocks) for a possible future San Mateo Rocks Lighthouse, and an act of Congress assigned ownership to the Bureau of Land Management in 1935,[7] but the lighthouse facility was never built.[5][4] In the early 1970s the waters around the rocks were a collection site for seaweed species in genus Gelidium for use in agar production.[8]
The rocks host a transient population of California sea lions.[9][10] Indigenous people may have used San Mateo Rocks as a pinniped hunting ground.[11] On one occasion this population of sea lions attracted a pod of orcas—quite uncommon in local waters—who used a clever pack-hunting technique to force the sea lions off the rock and into the water where they would be ready prey.[12] The rocks are a common destination for local dive boats.[13]
