About this map

Tiber Reservoir dominates this high plains landscape, formed where the Marias River was dammed in the decades following World War II. The map details a complex shoreline where the rising waters inundated the original river valley, creating deep inlets at Emerson Coulee and Bishop Coulee. Much of the surrounding terrain is marked by fine red dashed lines indicating selected fence lines, a testament to the large-scale ranching and land divisions in Liberty County.

Evidence of local habitation is sparse, centered on the Kolstad settlement. To the south, the terrain becomes increasingly dissected by dry drainage systems such as Timber Coulee and Pondera Coulee. The presence of a Picnic Area and a Gravel Pit near the eastern shore reflects the dual nature of the reservoir as both a recreational site and a utility of the regional infrastructure during the early 1970s.
