PORTLAND, Ore. (AP) — A marijuana growing operation that stretched about a mile in a remote ravine in the northeast corner of Oregon may turn out to be the largest ever shut down in the state.

Oregon State Police said Friday a raid in Wallowa County found more than 91,000 plants in a ravine with extensive terracing. Miles of plastic irrigation tubing lined the area, and authorities found weapons, food and supplies at campsites that could support growers for weeks.

Sgt. John Shaul of the La Grande police department describes the outdoor growing operation as "staggering," with plants concealed in several separate pods developed by removing trees and underbrush to camouflage the site.

Six men were arrested.
