Door/Kewaunee County Chapter

DOOR COUNTY
The Door Peninsula owes its existence to the hard dolomite (similar to limestone) of the Niagara Escarpment. This enormous arcing ridge can be seen on the east side of Horicon Marsh and Lake Winnebago, through Door County, Michigan, and Ontario, and forms the crest of Niagara Falls, New York. The Niagara Escarpment also separated the Lake Michigan and Green Bay lobes of the recent glaciation.

The eastern terminus of the Ice Age Trail is at the observation tower in Potawatomi State Park. Heading southwest, the Ice Age Trail coincides with the Ahnapee rail-trail. In southern Door County, it passes through drumlins, farms, wetlands and forests.

KEWAUNEE COUNTY
The Kettle Moraine reaches its northern extent in Kewaunee County. Most of the existing Ice Age Trail through the county coincides with the Ahnapee rail-trail. This brings the Trail to the City of Algoma on the shore of Lake Michigan. Algoma, which means "Hill of Flowers", was originally the site of a Potawatomi Indian village. By the late 1800's, Algoma boasted the largest commercial fishing fleet on Lake Michigan.

Carved by the gushing meltwater from Glacial Lake Oshkosh, the Kewaunee River Valley today is calm and scenic.
