1983 Map of Geddart Lake

About this map

Poplar River winds through the heart of this landscape in Roosevelt County, Montana, carving a complex series of oxbows and meanders across the plains. This 1983 provisional survey captures the hydraulic character of the region, where the river's path is flanked by intricate contour work showing the eroded breaks and bluffs common to this part of the state. The entire area shown lies within the boundaries of the Fort Peck Indian Reservation, highlighting a territory defined by expansive open terrain and the vital water source of the river. To the north, the drainage of Kirns Coulee feeds toward the river valley, while the namesake Geddart Lake sits as a quiet landmark among the upland draws. The map serves as a technical record of the land's surface at the time of field checking in 1977, illustrating the sparse but distinct natural features of the Missouri River basin's northern tributaries.
