2022 Map of Dorchester

About this map

Upper Iowa River and its intricate tributaries dominate this corner of Allamakee County, where the driftless landscape creates deeply carved valleys and sharp ridges. The settlement of Dorchester sits at a critical juncture where Waterloo Cr meets the main river valley, while the smaller community of Quandahl is positioned further west along Bear Creek. The map is particularly valuable for genealogical research, documenting numerous rural burying grounds that speak to the area's pioneer heritage, including the Swenson Farm Cem, O'Hare Place Cem, and the dual sites of Saint Johns Methodist Cem and Saint Marys Cem. A complex network of gravel and paved roads like Co Hwy W40 and Dorchester Rd trace the ridgelines and valley floors, illustrating how the topography has historically dictated movement and settlement patterns in this northeastern Iowa borderland.
