About this map

The Fort Peck Indian Reservation Boundary defines the southern portion of this landscape, where the Missouri River's influence is evident in the formation of Chelsea Island and the adjacent Chelsea Slough. The small settlement of Chelsea sits along the Burlington Northern railroad line, serving as a focal point for the surrounding prairie. This 1970s survey captures a rural landscape shaped by narrow drainage systems like Boxelder Creek and Chelsea Creek, which carve through the terrain north of the river.

Local history and genealogy are anchored by the presence of St Anns Chapel, St Anns Cem, and Boxelder Cem situated on the bluffs overlooking the river valley. The map also records early industrial markers such as a Gravel Pit and a prominent Pipeline crossing the territory. This documentation provides a clear view of the intersection between reservation lands, rail transport, and community infrastructure during this era.
