Lowland Periglacial Landscapes
Ecological Roles of the Chigmiut Glaciers
After you fly across Cook Inlet toward Wolverine Creek, you cross
an enormous alluvial plain, where bedrock is covered with a deep
layer of glacial till. As the glaciers retreated towards the nearby
the till.  When that ice melted, these became "glacial kettle hole"
lakes.  
West Foreland -- what remains of the western side of the
t
erminal moraine that once dammed Cook Inlet.
The above images from Google Earth do not have realistic colors, and provide
only a rough representation of what the land looks like.  For greater accuracy,
see the photos below provide.  First though, to help you better understand the
features you see in the photos or by flying over, check out these three diagrams.
Kettleholes  (site unknown_
Esker -- made of glacial debris deposited on the bed of a
river within the glacier or under it.  When the ice melted
away, this was left.  Eskers are higher than surrounding
for denning by wolves, coyotes, foxes, and perhaps bears.
