2017 Map of Humbolt Hills

About this map

Humbolt Hills dominates the central landscape of this borderland region, where the high plains of Montana meet the western edge of South Dakota. The terrain is defined by a network of drainage patterns and intermittent waterways, including the winding course of Boxelder Creek in the northwest and Spring Creek further south. This 2017 survey illustrates a sparse, wide-open landscape primarily utilized for ranching and transit, centered around the Carter County and Harding County line. Human infrastructure is limited but significant, centered on the corridor of Mill Iron Rd which traverses the southwestern quadrant. Topographic details such as Seal Draw reveal the intricate erosional features characteristic of this semi-arid environment, providing a clear record of the physical geography at the state junction.
