1975 Map of Mount Michelson C-3

About this map

Arctic National Wildlife Range defines the remote landscape of this 1970s revision, which incorporates data originally captured during the mid-1950s. The terrain is dominated by the massive east-west ridges of the Sadlerochit Mountains and the Shublik Mountains, which rise sharply from the surrounding coastal plain. Between these ranges, the Ignek Valley provides a natural corridor carved by Ignek Creek. Significant waterways, including the braided Tamayariak River and the meandering Katakturuk River, drain north toward the Beaufort Sea. The map depicts a pristine wilderness with no roads or trails, reflecting the untouched character of the North Slope Borough during this era. Surveyed before the major infrastructure of the oil era reached this specific interior sector, the sheet serves as a clear record of the area's natural drainage and geomorphology.
