Boulder County law enforcement, with the help of an Army National Guard helicopter, were airlifting bundles of dug-up marijuana plants out of South St. Vrain Canyon on Tuesday, Sept. 2, after a large-scale illegal marijuana grow was discovered in the area last week.

An undisclosed number of plants are being taken via Black Hawk helicopter from the grow location down to the Boulder County Transportation Yards, located at 5201 St. Vrain Road in Longmont near Vance Brand Airport, officials said.

The grow operation, discovered by hikers last week, was set up by an unknown person or persons on private property without the land owner’s permission, Boulder County sheriff’s Cmdr. Heidi Prentup said.

Sheriff Joe Pelle said initial estimates are that the operation included 400 to 500 plants.

The Boulder County Drug Task Force, Boulder County SWAT and U.S. Forest Service worked together on removal of the grow, the sheriff’s office said.
