2017 Map of Skagway C-4 NE

About this map

Mt Ashmun rises as the primary topographic landmark on this international boundary sheet, where the rugged interior of the Haines Borough meets the territorial line of the United States and Canada. This 2017 survey documents a high-latitude wilderness defined by glacial drainages and extreme vertical relief, largely untouched by permanent settlement or infrastructure. The cartography focuses on the complex drainage patterns and contour elevations of the boundary peaks, including the high ridges of t26s r54e and t26s r55e. It captures a transition zone where the administrative boundary of the Alaska Haines Borough interacts with the international border, providing a precise record of the remote terrain before environmental shifts further alter the northern landscape.
