San Diego-La Jolla Underwater Park

rdf:langString San Diego-La Jolla Underwater Park

rdf:langString The San Diego-La Jolla Underwater Park spans 6,000 acres (24 km2) of ocean bottom and tidelands. The park's four distinct habitats (rocky reef, kelp bed, sand flats, and submarine canyon) make it a popular destination for snorkelers and scuba divers. The park was created by the City of San Diego in 1970 and actually has two other parks within it: the "look but don't touch" Ecological Reserve and the Marine Life Refuge. Within the underwater park are two artificial reefs, created to attract and enhance marine life. The first was built in 1964 with Santa Catalina quarry rock dumped in 70 feet (21 m) of water near Scripps Canyon. The second was started in 1975 and is located at a depth of 40 feet (12 m) just offshore from Black's Beach. From La Jolla Shores, the ocean bottom slopes gently out to sea. The reefs keep the waves minimal, making this an entry point for divers and kayakers. Kelp beds on the outer edges of the slope are popular fishing spots and great for observing seals, dolphins, birds and fish. Beyond the slope the bottom takes a sudden and 500-foot (150 m)-deep plunge into the La Jolla Canyon. The canyon reaches depths of 600 feet (180 m) within the park. The abrupt drop and abundance of marine life help to explain why migrating whales can often be spotted close to shore. A 30-foot (9.1 m) by 75-foot (23 m) lithocrete map of the underwater park was completed in September 2008 at La Jolla Shores beach. It is located near the boardwalk between the restrooms and the children's play area at the south end of Kellogg Park.
