cantonment. Erosive activity (a)

Composed of Diamicton

during deposition of the Moun-

tain View fan cut through the

Dishno Pond ground moraine

and edges of the Elmendorff Mo-

raine. Erosion and deposition (b)

associated with the Mountain

View fan was accompanied by

sediment failure along the mar-

gin of the Elmendorf Moraine,

producing an interstratification

between sand and gravel and

Dishno Pond diamicton

would encounter a diamicton at

Fort Richardson diamicton

an elevation roughly equivalent
