1987 Map of Collins NW

About this map

Teton River meanders across the southern portion of this landscape, its winding course defining the lower topography of the High Plains. To the north, Muddy Creek carves a complex drainage pattern, joined by the distinctive Kropp Coulee. The terrain is characterized by the broad, low-lying Alkali Flat, a feature typical of the region's semi-arid basin ecology. This 1987 provisional survey shows the transition across the Pondera and Teton County line, documenting the hydrology and landforms before modern agricultural or infrastructure changes significantly altered the drainage basins. The map provides a high-resolution look at the intricate contour intervals and water distribution in this sparsely settled Montana territory.
