B. Eskers
Outwash from subglacial channels, created ESKERS which are linear forms of stratified sand/gravel deposit and typically extends along a major river valley. After the retaining ice walls melted away, the stream deposits remained as long winding ridges.
The Mason Esker, the longest esker in the Western Hemisphere, is located in Mason, Michigan. It stretches from DeWitt through Lansing and Holt, finally ending in Mason. Eskers are sometimes used for construction of highways as an economic measure. This includes the Denali Highway in Alaska and the Trans-Taiga Road in Quebec.
