About this map

Dewey Marsh dominates the landscape at the meeting point of Marathon and Portage Counties, creating a complex wetland environment where the Little Eau Claire River and Hay Meadow Cr originate. This 2018 survey reveals a terrain defined by glacial influence, where low-lying marshy expanses are punctuated by elevated features like the curiously named Philippine Islands and the rise of Blackberry Hill.

Small agricultural and residential clusters such as Rocky Corners and Ashley are connected by a grid of rural roads, including Co Rd C and S Co Rd X. These roads follow the section lines of the Public Land Survey System, illustrating how human settlement patterns have adapted to the saturated soils. Local names like Zoromski Rd, Rucinski Rd, and Kolodziej Ln suggest a lineage of family ownership and regional heritage tied to the development of these Wisconsin lands.
