Denver authorities say hunters discovered about 1,000 mature marijuana plants valued at $500,000 at an elaborate growing operation in Golden Gate State Park.
Law enforcement, wildlife and parks workers harvested the plants this week, and a helicopter lifted them in bundles from the remote location.
Detectives found a nearby camp, including a tent, food, clothing and sleeping bags, the Denver Post reported Wednesday.
No one has been arrested, and authorities ask anyone with information to contact the Jefferson County Sheriff’s Office at 303-271-5612.
Three other marijuana-growing operations have been discovered in Jefferson County this year, officials said.
