1956 Map of Eagle A-6

About this map

Mt Harper dominates the northwestern corner of this 1950s landscape, serving as a prominent landmark in a region defined by its complex drainage systems. The map illustrates a wilderness characterized by the winding courses of the Middle Fork Fortymile River and the Healy River, which carve through the terrain before the later era of more intensive resource mapping. Surveyed primarily through aerial photography from 1954 and 1957, these land lines represent unsurveyed and unmarked locations predetermined by the Bureau of Land Management. The absence of roads or established settlements at this time highlights the remote nature of the territory south of Sand Creek, where the river-and-creek network provided the primary means of orientation for early explorers and surveyors in the Alaska interior.
