During two two-day periods in mid-December, rangers from Point Reyes, working with other local law enforcement agencies and supported by the National Guard, removed trash from five marijuana cultivation sites in the park and 10 other sites on surrounding lands. Over 70 cubic yards of garbage were removed, including more than 10 car batteries, six pesticide sprayers, 10 propane tanks, and over 150 pounds of fertilizer. The garbage was gathered in the sites, then removed by helicopter sling load. All of the marijuana sites discovered in the park this year have been cleaned up and rehabilitated to minimize resource damage and deter future growing operations.
