1952 Map of Iona NW

About this map

The confluence of the White River and the Missouri River dominates this mid-century landscape along the border of Lyman and Brule Counties. This survey documents the river valley before the rising waters of the Fort Randall Reservoir altered the shoreline, as indicated by the blue submerged area lines. The topography transitions from the alluvial plains of Peterson Bottoms to the dissected bluffs of the Oacoma and Iona districts. Evidence of rural life is concentrated in localized ranching complexes such as Close Ranch and Glaus Ranch, while the presence of the Walker Sch and the Grandview Sch (Abandoned) marks the shifts in local education and settlement. The land is punctuated by numerous Flowing Wells, vital for sustaining operations across this river-basin terrain.
