About this map

Dennys River flows through this corner of Washington County, defining a landscape shaped by water and timber resources in the late 1980s. The map illustrates the rural character of the region, where small settlements like Pine Corner and Marion are linked by winding roads through wooded terrain. The drainage of Gilman Brook, supported by the Gilman Dam, joins the river near Gardner Rips, highlighting the significance of the waterway's descent and the local importance of these specific river features.
