1985 Map of Clay Center

Away from the river bottoms, the terrain rises toward distinctive landmarks like Table Mounds and Tobyne Hill. The map meticulously records the infrastructure of the era, from the Clay Center Muni Airport to the numerous quarries and a Sandpit scattered across the plains. For those researching the region's environmental history, the Ottawa County State Fishing Lake and Wildlife Area provides a look at conserved prairie and wetland habitats as they existed in the mid-1980s.
