Alton and Granville anchor this agricultural landscape in northwestern Iowa, where the high prairie is defined by a rigorous section-line road grid. The boundary between Sioux Co and Plymouth Co runs horizontally across the lower third of the quadrangle, marked by 510th St. This area is characterized by the headwaters of several drainage systems, including the southward-flowing Willow Creek and the eastward-trending Granville Creek. The map documents a landscape almost entirely shaped by modern commercial farming, with a dense network of local routes like Co Hwy B62 and 460th St connecting the scattered farmsteads that populate the townships of t94n r44w and t94n r43w. The survey provides a clear view of how political boundaries and transport corridors intersect with the natural flow of Deep Creek near the southern border.
