Calumet Shoreline

The shoreline is named after the Calumet Region of Northern Indiana.

[1] The Michigan Lobe of the continental glacier had been stagnant for years, forming the Glenwood Shoreline.

The melt waters which formed Glacial Lake Chicago, had more space in which to reside.

It appears that the outlet to the Illinois River, was cutting downward, keeping pace with the lowering lake.

It takes its name from the Calumet River in northwestern Indiana where it is well preserved.
