The National Park Service cleared out half a ton of trash and chemicals last week from an abandoned marijuana growing operation in the Point Reyes National Seashore. The site was discovered on March 8 near the Laguna Trail, which begins near the hostel and the Clem Miller Environmental Education Center and ends at Coast Camp. A team of park employees and volunteers from Conservation Corps North Bay began cleaning up the site in the spring, and last month park rangers and trail crew members cleared the area for a helicopter to land. The work was completed last Thursday. Growers had left behind old cultivation equipment, piles of trash and a dam in a nearby creek. Rangers also discovered a pellet rifle and multiple containers of herbicides and pesticides at the site, located in the park’s 33,373-acre Philip Burton Wilderness.
