The Floyd River and its tributary, the West Branch Floyd River, define the agricultural and urban landscape of this Plymouth County region. Le Mars serves as the primary hub, showing a well-developed street grid that includes Lincoln St SW and Plymouth St E, alongside municipal infrastructure such as the Le Mars Municipal Airport. The map captures the town's expansion toward West Le Mars and the smaller community of Seney to the northeast. Several significant burial sites are documented across the quadrangle, including Le Mars Memorial Cem, the Seney City Cem, and Saint Josephs Catholic Cem, providing valuable data for genealogical research. The surrounding terrain is heavily partitioned by a network of rural roads like Kestrel Ave and Co Rd C16, reflecting the section-line organization of Iowa's farmland.
