Closer to the lake from the Calumet Shoreline, there are the Tolleston shorelines and farther from the lake are the Glenwood Shoreline, the Tinley Moraine, and the Valparaiso Moraine. The shoreline is named after the Calumet Region of Northern Indiana. Development The Michigan Lobe of the continental glacier had been stagnant for years, forming the Glenwood Shoreline. Once again, it began a general retreat northwards. The melt waters which formed Glacial Lake Chicago, had more space in which to reside. Then it began to drop. It appears that the outlet to the Illinois River, was cutting downward, keeping pace with the lowering lake. At around , it stopped cutting downward and the lake stabilized.
