Okanogan National Forest covers this high-altitude landscape of the North Cascades, centered on the prominent massif of Robinson Mountain. The map illustrates a recreational and backcountry infrastructure existing in the early 1960s, featuring several established sites along the river corridors such as Ballard Campground and Rivers Bend Campground. The remote nature of the terrain is emphasized by the presence of the Lost River Landing Strip and primitive outposts like Porcupine Camp.
