The Sugar River meanders through the southern half of this landscape, forming a wide, fertile valley that historically defined the development of Rock County. Settlement patterns here are anchored by the town of Brodhead in the northwest and Orfordville in the northeast, connected by a network of rural roads that serve the surrounding agricultural townships of Spring Valley and Avon. This 1962 survey, updated with 1971 aerial data, captures the rural infrastructure of the mid-century, including the Chicago Milwaukee St Paul and Pacific railroad corridor and local social centers like the Avon Townhall.
