2017 Map of Selby SW

About this map

Sitka serves as the primary landmark in this section of the South Dakota plains, situated along the southern edge of a landscape defined by geometric section lines and expansive drainage basins. The northern portion of the map is dominated by the Blue Blanket Lakebed, a sprawling hydrological feature that underscores the seasonal and shifting nature of water in the Missouri River valley region. The terrain transitions from the high, flat plateaus in the south near Sitka to the broad, marshy depressions of the lakebed to the north.
