1970 Map of Dewey Marsh

USGS Topo · Published 1990

About this map

Dewey Marsh dominates this landscape along the border of Marathon and Portage counties, creating a complex wetland environment where the Little Eau Claire River and Hay Meadow Creek converge. The topography of 1970 reveals a fascinating mix of low-lying marshland and abrupt glacial rises. One of the most distinctive features is the Philippine Islands, a series of small landforms rising out of the marsh waters, while to the northeast, Blackberry Hill stands as a prominent high point.
