Several retreating unnamed, small valley glaciers and several recently deglacierized cirques and ridges east of the terminus of Tonsina Glacier, northcentral Chugach Mountains, Alaska. Much of the ice disappeared during the last few decades of the twentieth century. Note the fresh moraine deposits. Photograph by Bruce F. Molnia, USGS.

The retreating terminus of Stephens Glacier with several of its retreating unnamed valley glacier tributaries. The easternmost former tributary lost contact with Stephens Glacier during the later part of the twentieth century. Northcentral Chugach Mountains, Alaska. Note the fresh moraine deposits on the valley floor. Photograph by Bruce F. Molnia, USGS.

North view of the terminus and lower reaches of Valdez Glacier, a rapidly thinning and retreating valley glacier located northeast of Valdez, northcentral Chugach Mountains, Alaska. Note the trimlines and the enlarging ice-marginal lake exposed at the margin of the glaciers. During the twentieth century, Valdez Glacier thinned by more than 300 feet. Photograph by Bruce F. Molnia, USGS.
