Agricultural research and railway hubs define this central Iowa landscape during the mid-1970s. The Iowa State University Experimental Farms occupy significant acreage in the northern section, highlighting the region's academic and scientific ties to farming. Transportation is anchored by the crossing of the Chicago and North Western and the Chicago Milwaukee St Paul and Pacific railroads, which facilitated the growth of towns like Slater and Kelley. Small aviation hubs such as the Erickson Landing Strip and another unnamed Landing Strip near the Boone and Story County line indicate the local importance of private flight. Rural life is anchored by local landmarks like the Bethany Cem and Zumwalt Station Park, while Ballard Creek and Walnut Creek drain the surrounding fields toward the larger river basins beyond this survey's borders.
