Agricultural life in central Iowa's Grundy and Marshall counties is clearly documented in this mid-century survey. The landscape is defined by the drainage patterns of Wolf Creek in the north and the winding course of Asher Creek and Little Asher Creek further south. A notable remnant of earlier transportation infrastructure appears as an Old Railroad Grade cutting across the northern portion of the map, suggesting the evolution of the local transit network. Near the town of Conrad, a prominent Quarry indicates the area's local extraction industry.
