The Sonoma County Sheriff's Department received a report of possible trespassers from a property owner in the Mill Station Road area, north of Sebastopol, around 11 a.m.
Deputies checked the area and found the marijuana garden, which was estimated to be worth several million dollars. They also found hazardous pesticides and fertilizers.
Sheriff's deputies flying overhead in a helicopter spotted two men fleeing the area, but lost them in the thick underbrush. Deputies took a sample of the plants for evidence and destroyed the rest.
The Sheriff's Department is warning property owners and people who are involved in outdoor recreation that marijuana gardens can be extremely dangerous. They usually do not belong to the property owner and are sometimes guarded by people with high-power weapons or booby-traps, according to the sheriff's department.
Anyone with information about the suspects is encouraged to call the Sheriff's Department at (707) 565-2650
