2013 Map of Observatory Hill

About this map

Glen Oak sits in the northern reaches of this rural landscape, which is defined by a dense network of minor waterways and small basins. The terrain is dominated by Observatory Hill and characterized by its unique hydrography, featuring multiple distinct water bodies including Madden Lakes, Knights Lake, and Dates Millpond. These water features feed into systems like French Cr and Belle Fountain Cr, reflecting a region deeply tied to its glacial drainage patterns. The convergence of Wi-22 with county routes such as Co HWY-B and Co HWY-O suggests a community structure oriented around agricultural transit and local connectivity. In the northeast, the Grand River and Fox River brush the edges of the sheet, further anchoring the area as a significant riparian corridor in Marquette County.
