2017 Map of Chelsea

About this map

Chelsea sits at the southern edge of this Missouri River landscape, where the shifting river channel has created distinct landforms like Chelsea Island and the adjacent Chelsea Slough. The topography is defined by the winding course of Boxelder Cr, which cuts through the plains from the northwest before reaching the Missouri valley. This 2017 survey by the U.S. Geological Survey highlights the essential road network of the Poplar District, including Bia Rte 1 and Red Thunder Rd, which connect the rural landscape. For genealogists and local historians, the map provides precise locations for Saint Ann's Cem and Boxelder Cem, situated on the rising ground north of the river. The surrounding terrain is marked by smaller seasonal waterways like Little Badger Cr and Chelsea Cr, illustrating the drainage patterns of this eastern Montana prairie.
