Redoubt is one of the two most active volcanoes of the upper Cook Inlet region, viewed here from the north in 1980. Drift glacier flows from the summit into the Drift River valley. Thick lava flows partly form the summit and Holocene lahars have filled the Drift River valley to the NE and Crescent River valley to the SE.
