2015 Map of Flandreau SW

About this map

Egan sits in the southeast corner of this Moody County landscape, positioned along the Big Sioux River just before it meanders out of the quadrangle. The terrain is defined by the Coteau des Prairies, a high glacial plateau that creates a distinctive drainage pattern across the region. Several tributaries, including Squaw Cr and Spring Cr, cut through the section lines, reflecting the natural hydrography that guided early settlement. Genealogists and local historians will find the locations of North Clare Cem and Clare Cem valuable for tracing family roots in this rural township structure. The map detail highlights the rigid section-line road network, such as 227th St and 476th Ave, which delineates the agricultural heritage of this South Dakota prairie.
