History
Archeologists have found traces of human occupation on the San Clemente Island dating back 10,000 years, a remarkable figure for an island 55 nautical miles (102 km) out to sea, but consistent with results on other Channel Islands.
Later inhabitants left trade materials from the northern islands and from the mainland, including
Coso obsidian from the California desert. It has not been established what tribe the recent inhabitants belonged to,
although the
Tongva, who are well attested from
Santa Catalina Island, are the most likely candidates. The
Chumash, who occupied the northern Channel Islands, may have influenced the inhabitants.
The island was named by
Spanish explorer
Sebastian Vizcaino, who spotted it on
November 23,
1602,
Saint Clement's
feast day. It was used by ranchers, fishermen, and smugglers during the 19th century and into the 20th century.
The city of
San Clemente in
Orange County, California is named after the island.

Navy base
The U.S. Navy acquired the island in 1934. It is the Navy's only remaining ship-to-shore live firing range and is the center of the integrated air/land/sea
San Clemente Island Range Complex covering 2,620 nm² (8,986 km²).
It is an active
sonar base and has a $21 million simulated
embassy for
commando training.
There is also a U.S. Navy
rocket-test facility on San Clemente. It is situated at . Some
Polaris-program test rockets were launched from San Clemente between 1957 and 1960.
Wildlife
The
San Clemente Island Loggerhead Shrike is an
endangered species that the Navy is taking steps to protect. The
San Clemente Island Fox is an
indigenous species.
Feral goats roamed the island for centuries, reaching a population of 11,000 in 1972, when their effect on indigenous species was realized. By 1980 the population had been reduced to 4,000. A plan for shooting remaining goats was blocked in court by the
Fund for Animals, so the goats were removed with nets and helicopters. The
San Clemente Goat is a recognized breed of domestic goat. The coves around the island are visited by divers attracted by the abundant sea life, including
sea lions,
lobsters,
hydrocoral and
kelp forests.
