2012 Map of Ortley

About this map

Ortley serves as the primary center of activity in this part of Roberts and Day counties, organized around a grid of streets including Ash St and Oak St. The town's historical footprint is anchored by the Ortley Cem to the south. This landscape is defined by the headwaters and drainage patterns of the Big Sioux River, which winds through the southern portion of the quadrangle. The surrounding prairie is dotted with significant glacial features typical of the Coteau des Prairies, most notably Bill Smith Slough and Pearson Slough. Further west, Anderson Lake marks a low point in the terrain. The area's rural character is maintained by a rigid network of section roads like 139th St and 450th Ave, reflecting the enduring township and range survey system that shaped local land ownership and travel.
