GREAT FALLS, Mont. (AP) — Members of a drug task force harvested 35 large marijuana plants from a grow operation on the banks of the Sun River in western Great Falls.

After receiving a tip, Great Falls police began surveillance on the property because it appeared someone was tending to the plans.

On Wednesday night, agents with the Russell Country Drug Task Force harvested the plants, which have an estimated value of between $35,000 and $40,000.

No arrests have been made.
