Glenwood Shoreline

After the straits were freed, the lake receded and left behind a sand ridge at an elevation of about 640 feet (200 m) where the shore resided.

The melt waters began to form a lake between the southern front of the glacier and the moraine, which acted as a dam.

The water collected until it found a low spot in the moraine, near modern Palos Hills, Illinois.

At around 640 feet (200 m) above sea level, it stopped cutting downward and a stable lake formed.

When the beach reaches10 miles (16 km) north of the Muskegon River it returns to the shore of Lake Michigan.

Beginning in Dyer, Indiana, along U.S. Route 30, the beach continues eastward from where U.S. 30 bends southward just east of U.S. 41.

The next segment can be found west of State Route 51 in Hobart, along the southern flank of Deep River.
