About this map

Wrangell-Saint Elias National Park encompasses this high-altitude Alaskan wilderness, where the drainage of the Bremner River system shapes the topography. The map illustrates a complex network of glacial meltwater and alpine streams, including the Little Bremner River and its East Fork. These watercourses flow through a landscape largely protected within the Wrangell-St. Elias Wilderness, a region defined by its lack of human infrastructure or established roads.

A boundary line for Copper River County and Chugach County bisects the northern half of the sheet, providing a rare administrative marker in this otherwise natural expanse. Near the center of the quadrangle, Salmon Creek joins the larger river system, highlighting the hydrological patterns of the Chugach Mountains. This 2023 survey serves as a modern baseline for studying the shifting glacial valleys and hydrography of one of the nation's most remote protected areas.
