About this map

Wrangell-Saint Elias National Park encompasses much of this interior Alaskan landscape, which transitioned between Copper River Co and Chugach Co jurisdictions. The terrain is defined by dramatic elevation changes, where high ridges overlook deep-set watercourses like Twelvemile Canyon and Harrys Gulch. This 2023 survey illustrates the glacial and fluvial drainage patterns common to the region, most notably the winding path of the North Fork Bremner River in the southeast corner. The vast protected area within the Wrangell-St. Elias Wilderness remains largely untouched by development, focusing on natural features such as Sangaina Creek and Lake Creek. These features underscore the extreme isolation of this mountainous territory, where steep contours rise from valley floors to high alpine peaks without the presence of modern road infrastructure.
