in a piedmont ice-sheet—the Malaspina Glacier—whose area exceeds 
1,500 square miles. Most of this area is clear ice but where parts of 
the border are stagnant they have been covered by ablation moraine 
upon parts of which forests have grown. ‘This is the largest glacier in 
the world outside the Arctic and Antarctic regions. 
The east half of the model shows a series of fiords with cirques, 
hanging valleys, etc., produced by ice-erosion when the glaciers were 
more extensive, as well as the glacial coastal plain known as the 
Yakutat Foreland. Marginal lakes, medial, lateral, terminal, and 
recessional moraines, and outwash plains are shown.
