About this map

Glacial geology and early settlement patterns define this portion of the Jackson Co and Washtenaw Co border in the early 1970s. The northern half is dominated by the Waterloo State Recreation Area, a landscape characterized by the vast Portage Lake Swamp and the Portage River. Small communities like Waterloo and Trist are situated near water features such as the Trist Millpond and Clear Lake, illustrating the historic reliance on local hydrology for power and community center-points.

Further south, the terrain rises toward Sackrider Hill before descending into the basin surrounding Grass Lake and Tims Lake. Evidence of former transport networks is visible in the Old Railroad Grade passing through the recreation area. Local institutional and family history is preserved through markers like Mt Hope Ch, the Michigan Baptist Assembly Camp, and several burial grounds including Mt Hope Cem and East Cem. The presence of numerous Gravel Pits reflects the area's ongoing extractive land use alongside its recreational development.
