2021 Map of Academy

About this map

The Missouri River valley in South Dakota is dominated here by the expansive waters of Lake Francis Case, where the Platte-Winner Bridge crosses the water near the southern edge of Charles Mix County. The landscape transitions from the river bluffs to the high plains, marked by the small settlement of Academy and the communal layout of Platte Colony. Local history is anchored by the LaRoche Cem, which sits north of the colony near the winding course of Snake Cr. The road network follows a strict sectional grid, with numbered avenues and streets like 355th Ave and 270th St providing the structure for this agricultural region. This survey captures a rural landscape where traditional settlements and modern infrastructure meet at the river's edge.
