About this map

The Fort Peck Indian Reservation dominates the northern landscape of this region, where the Great Northern railroad tracks parallel the north bank of the Missouri River. Surveyed between 1908 and 1910, the topography illustrates a transition between the wide river valley and the dissected uplands to the south. Small settlements like Chelsea and Nickwall serve as local anchors, while the southern boundary of the reservation follows the river's meandering course. A significant Boundary Line separates Valley County and Dawson County, cutting directly through the Missouri's channel. The map records the early 20th-century hydrology of the area, featuring drainage systems such as Redwater Creek, Boxelder Creek, and Chelsea Creek. The presence of Burch in the southwest corner and various benchmarks throughout the terrain suggests an era of active land measurement and homesteading along the river corridor.
