Rangers raided a marijuana farm inside Sequoia National Park on Wednesday 9 August 2006, removing 2,152 marijuana plants with an estimated value of $2 million.[1] The plantation sat within view of Moro Rock, a major park feature visited by hundreds of people a day.[1][2] The park received help during the operation from Pinnacles National Monument, Yosemite National Park and Mojave National Preserve, with regional special agents assisting.[1]

There were no arrests associated with the raid, but the investigation continued.[1] The raided plants included several strains that appeared genetically altered, with only three leaves, shorter stalks under three feet and faster maturation that could allow more than one crop a season.[1] Sequoia-Kings Canyon had spent more than $72,000 over two years cleaning up 81 cultivation sites covering 10 acres, and authorities had seized more than 100,000 marijuana plants in the parks since 2004.[2]
