CAMP SHERMAN, OR -- The Green Ridge Fire is 4,338 acres and 85% contained. The fire team expects to be at 100% containment by Wednesday. Greenridge Fire officials also reported a drone flying over the area Sunday night. Public Information Officer Tom Fields, says firefighting aircraft must land if drones are spotted near a wildfire for safety reasons. He says to operate a drone near a wildfire interferes with the effort to fight the fire and is illegal. This can lead to a serious fine and/or court appearance. Fields says a drone can compromise firefighter and public safety.
