1961 Map of Sandstone

Genealogists will find significant detail in the distribution of rural institutions, including the Dell Grove Ch and various family-named sites such as Koivisto Sch. The map also documents the transition from industry to conservation, noting the Fish Hatchery near the confluence of the Grindstone River and the river valley. Numerous gravel pits and small lakes, like Fish Lake and Indian Lake, dot the townships, illustrating the glacial topography of the St Croix State Forest region.
