Caption:Lahars formed during the 1989 to 1990 eruptions of Redoubt Volcano accumulated in the Drift River valley. The largest lahars, such as this one from the February 15, 1990 eruption, covered the valley floor nearly wall to wall and extended more than 35 km (22 mi) to the Cook Inlet. View is to the west. Photograph by T. Miller, U.S. Geological Survey, February 15, 1990.

RedoubtDebris flow/mudflow/landslide/lahar
thumbnail
Caption:On February 15, 1990, collapse of the 2nd largest lava dome of the 1989-90 eruption of Redoubt Volcano generated a large pyroclastic flow and surge that swept north across the piedmont lobe of Drift Glacier and up and over the adjacent ridge (nicknamed Ptarmigan Ridge for a dead ptarmigan found on top). This image shows deposits from the surge that traveled up and over the ridge. Redoubt volcano is located off the image to the right.
