Glaciers
Eklutna glacier covers about 50 percent of the West Fork basin. The glacier is currently about 8 miles long; its source is the slopes of peaks at about 6,000 ft altitude. In 1957, the terminus was at about 1,200 ft; during field observations in 1988, it was at approximately 2,400 ft [although the equilibrium line altitude remained at approximately the same altitude]....
Two watersheds account for more than half of the Eklutna Lake drainage basin. The East Fork Eklutna Creek basin is 38.2 square miles in size, of which 20 percent is consists of glaciers. The West Fork Eklutna Creek basin is 25.4 square miles in size, of which about 50 percent consists of glaciers...
Eklutna Lake occupies an elongated, glacially steepened depression dammed by a recessional terminal moraine of Eklutna Glacier. This glacial lake is fed primarily by inflow from the East Fork and West Fork Eklutna Creeks....
Both the East Fork and the West Fork Eklutna basins lie entirely within the Chugach Mountains and are developed primarily in structurally complex and variably metamorporphosed sedimentary and igneous rock. The topography is rugged and the glaciers are surrounded by cliffs and gullies....
