2014 Map of Chelsea SW

About this map

The Missouri River forms a major geographical and administrative boundary here, separating Roosevelt Co and McCone Co in this 2014 survey. North of the river, the landscape is defined by the drainages of Tule Creek and Chelsea Cr, with infrastructure dominated by Bureau of Indian Affairs routes such as Bia-1 and Bia-5. South of the river, the terrain shifts into a series of drainages and ridges, including the headwaters of Nickwall Cr and the smaller Rermley Cr. This area is characterized by more isolated rural roads, most notably Nickwall Rd, which traverses the southern portion of the quadrangle. The map captures a largely undeveloped portion of the Missouri River valley, showing the relationship between the river's path and the township and range grid system.
