Authorities have uncovered a 34,000-plant marijuana farm in " _mce_href="null" target="_self">Topanga State Park -- the largest such operation found in the Santa Monica Mountains in seven years.

Law enforcement officials raided the site Friday after park rangers found a plastic-lined earthen dam diverting water from a Topanga Creek tributary to a marijuana cultivation site deep in the park's backcountry, said Craig Sap, Angeles District Supt. for California State Parks.

Officials destroyed an estimated $100-million worth of marijuana, mostly young plants about 1 to 2 feet tall. The raid was carried out by a team of state park rangers, Los Angeles County sheriff's deputies and officials with the Mountains Recreation Conservation Authority.

No arrests were made, Sap said, though three men were seen fleeing the scene.
