The town of Ryan serves as the primary hub in this agricultural landscape on the border of Delaware and Linn counties. The region is defined by a dense network of country roads, including Co HWY d47 and Linn-Delaware Rd, which carve out a patchwork of farmsteads and rural properties. This survey reveals a high concentration of historical burial sites, such as Peace Cem, Golden Prairie Cem, and Calvary Cem, reflecting the deep roots of the local farming community.
