2012 Map of Arminto NW

About this map

Isolated cattle and sheep operations define this high-desert landscape in Natrona County during the early 2010s. The region is marked by historic grazing lands, with family-named outposts such as Sullivan Ranch and Todd Ranch established near the few reliable water sources available. The drainage patterns are dominated by seasonal flows like Alkali Cr and Poison Cr, whose names reflect the mineral-heavy water common to this part of the Wyoming Basin. In the southern reaches, Wight Ranch and Jack Ranch sit near the transition to Garrison Draw, showing how human settlement in this arid environment remained tied to these specific creek beds and the shelter of the terrain long after the initial frontier era.
