Iowa State University anchors the southeastern corner of this mid-1970s survey, showing the campus footprint alongside the ISU Arboretum and the Ames Laboratory Research Reactor. The transition from the urban grid of Ames to the surrounding agricultural landscape is clearly defined, with the Chicago and North Western railroad corridor cutting through the terrain. To the west and north, smaller settlements like Ontario and Gilbert maintain their distinct identities, while the Iowa State University Experimental Farm illustrates the region's academic and agricultural integration.
