1970 Map of Beaver D-6

About this map

The Jim River flows through this interior Alaskan wilderness, as documented during a 1970 survey of the Yukon-Koyukuk region. This topographic study reflects a landscape dominated by complex drainage patterns, with Lansing Creek feeding into the main river from the northeast. The terrain is defined by its watercourses, including Keating Creek and Granite Creek, which carve through the high elevations of the Beaver quadrangle. This map represents an era of land management where boundaries were largely predetermined and unsurveyed, as noted by the Bureau of Land Management. The absence of roads or trails on the sheet emphasizes the undeveloped nature of the central Alaska interior during the early 1970s, making it a primary record for those studying the natural hydrology of the area before modern infrastructure.
