Braided outwash -- Mt. Rainier, Washington

Continental Glaciers

Continental glacier terminus -- shows cross-section of glacier. Evans Is, Antarctica
Continentally glaciated rock -- very low relief, no soil. Near Thule, Greenland
Glacial till -- very compact, laid down beneath massive ice sheet. Malaspina Glacier, Alaska
Drumlin -- aerial view from side. Near Sebus, New York
Drumlin -- same drumlin as above, aerial view downstream along its axis
End moraine with kettles -- outwash plain in background. Near Polson, Montana
End moraine with erratics -- limit of continental glaciation in eastern Washington
Kettle lakes -- from melting of buried ice blocks. Cape Cod, Massachusetts
Esker, delta kame and grooved ground moraine (till) -- freshly formed. Wadsworth Glacier, Alaska
Esker -- aerial view of sinuous esker near Mansfield, Washington
Esker deposits -- roadcut through the esker above showing fluvial gravels. Near Mansfield, Washington
Continental glacier outwash deposits -- great thickness of fluvial sand and gravel. Fidalgo Is, Washington
Drowned coastline -- submerged coastline due to postglacial rise in sea level. Brunswick, Maine
Thermal regimes of continental glaciers -- diagram
Map of glaciation in the Northern Hemisphere
Glacier and vegetation distribution in the US -- last glacial maximum
