Law enforcement agents in California removed thousands of illegal marijuana plants from a 13-acre grow site hidden among one of the state's vast wilderness areas.

Rangers from the National Park Service joined Bureau of Land Management agents recently removed more than 2,300 marijuana plants and 2,000 pounds of trash and infrastructure from Sequoia National Park, according to an Aug. 21 press release. Investigators also uncovered a semi-automatic pistol and a gallon of a toxic banned insecticide, Methamidophos, during the operation.

The National Park Service said rangers had detected and raided this cultivation site in 2024, but were unable to rehabilitate the site until mid-August of this year due to the presence of hazardous chemicals.
