2022 Map of Colesburg

About this map

Turkey River winds through the northern reaches of this landscape where the borders of Clayton, Delaware, and Dubuque counties converge. The settlement of Osterdock serves as a focal point near the river, while further south, Colesburg marks a significant crossroads near the headwaters of Bloody Run. The terrain is defined by its deep drainages, including Devils Hollow and White Pine Hollow, which illustrate the erosion patterns characteristic of this corner of Iowa. This area is notably dense with small family and community burial grounds, such as Lewis Cem, Koenig Cem, and Noggle Cem, offering a detailed map of the region's genealogical footprint. Smaller hamlets like Fairview and Updegraff are linked by a network of rural routes, including Co Hwy C53 and Co Hwy X41, showing the persistence of these early agricultural communities into the modern era.
