2010 Map of The Arch

Settlement patterns in this arid region are sparse and utilitarian, centered on isolated outposts such as Larios Camp and the expansive Diamond A Desert. These locations reflect the area's history of ranching and resource management in a climate where water sources like the Jarbidge are the primary lifelines for both livestock and land use. The map illustrates a network of primitive roads connecting these remote sites, highlighting the logistical challenges of the southern Idaho backcountry in the early 21st century.
