2022 Map of Observatory Hill

About this map

Observatory Hill rises above a landscape defined by the winding courses of the Grand River and the Fox River at the boundary of Marquette and Columbia counties. The area is characterized by significant wetland systems and small water bodies such as Mulhern Lake and the Madden Lakes. The settlement of Glen Oak sits in the northwest, while the southern portion of the map is marked by the Dates Millpond on French Creek. This region maintains a strong connection to its pioneer roots, visible in the distribution of community landmarks like the Greenwood Presbyterian Cemetery and the North Marcellon Cemetery. The network of country roads, including County Highway O and County Road B, connects these rural outposts across a terrain of glacial drumlins and river bottomlands.
