1959 Map of Arapahoe

Settlement is concentrated around Arapahoe and St Stephens, with the Chicago and North Western railroad providing a vital transport corridor across the northern half of the quadrangle. To the south, the terrain rises into the Prospect Area and the winding course of Beaver Creek, where the land is marked by natural features like Preacher Draw and Sand Gulch. Local heritage is preserved in sites such as the Arapahoe Cemetery and the Arapahoe Catholic Cemetery, alongside several gravel operations and gauging stations.
