Larb Hills rise above a landscape defined by deep drainage patterns and remote cattle country along the Phillips and Valley County border. This terrain is characterized by a series of named coulees, including Dead Horse Coulee, McNab Coulee, and Pack Rat Coulee, which illustrate the complex erosion and water-scarce geography of the region. Transportation is limited to functional routes such as Larb Creek Rd and the Harb Trl, connecting isolated points like Spencer Point to the broader area. The intermittent flows of Larb Creek and Third Cr dictate the movement of both people and livestock across the high plains. This 2017 data reflects a modern era of land management where access is dictated by primitive roads and established property lines between the two counties.
