1955 Map of De Long Mountains

About this map

Brooks Range peaks and the coastal waters of the Chukchi Sea define this remote Alaskan landscape during the mid-1950s. The northern reaches of the De Long Mountains are documented here in high detail, showing a complex network of waterways including the Pitmagea River, Kukpuk River, and the Wulik River. Along the coast, Cape Sabine and Corwin Bluff stand as prominent landmarks for navigation, while the presence of the Thetis Mine near Kogituk Creek indicates early resource exploration in this Arctic frontier. Land travel is depicted via a Winter Trail and a generic Trail that skirts the Noonuklook Mountain foothills. This sheet is particularly useful for geologists and researchers tracing the naming of topographic features like Deadlock Mountain and Amphitheatre Mountain, as it records the drainage patterns and peaks before more modern infrastructure ever touched the region.
