2023 Map of Valdez A-2 SE

About this map

The Bremner River system dominates this Alaskan landscape, where the braided waterways and glacial outflows carve through protected lands. Part of the Wrangell-Saint Elias National Park and the adjacent Wrangell-St. Elias Wilderness, the area showcases a complex hydrological network. Significant water features include Steamboat Lake and the elongated Harnell Slough, which lie in the wide valley floor south of the mountains. This 2023 survey documents the intersection of the Copper River County and Chugach County boundaries. Tributaries such as Porcupine Creek and MacCreel Creek feed into the larger river basins, illustrating the drainage patterns of this high-latitude wilderness. The map provides a detailed view of the Little Bremner River as it winds through the transition from high-elevation peaks to the river flats.
