2011 Map of Chelsea

About this map

Boxelder Creek meanders through this portion of the Fort Peck Indian Reservation, defining the drainage patterns of the eastern Montana plains. The settlement of Chelsea sits near the southern edge of the sheet along the Missouri River floodplain, marked by the nearby Chelsea Slough and the winding Chelsea Creek. This landscape is characterized by a network of local water management features, including the Dolezilek Reservoir Dam, Wilma Dam, and Aytolloha Number 1 Dam, which support the region's agricultural and ranching operations. For those researching local heritage, the map identifies significant burial sites including Saint Anns Cemetery and Boxelder Cemetery, providing specific locations for these community landmarks. The infrastructure of the area is tied together by the Indian Hwy and the local Chelsea Loop Rd, which provide access across the wide drainage of Little Badger Creek and the surrounding rangeland.
