About this map

The Maple River valley dictates the geography of this Monona County region, where the town of Castana is situated at the intersection of local routes like Co Hwy E34 and Co Hwy L20. The landscape is characterized by a series of significant topographic features, including Granger Hill and Durr Hill, alongside numerous named hollows such as Gingles Hollow, Nutt Hollow, and Dutch Hollow. These landforms provide a clear view of the drainage patterns feeding into Cottonwood Cr and Arcola Cr.

Family history researchers can find several established burial grounds across the township, including Kennebec Cem, Bisbee Cem, and Belvidere Cem. To the southwest, the settlement of Turin sits near the confluence where the Little Sioux River and Maple River floodplains meet. The map detail extends to specific landmarks like Green Valley and the winding course of Gard Cr, offering a precise record of rural Iowa’s road network and land divisions in the modern era.
