2021 Map of Bradfield Canal B-3 SW

USGS Topo · Published 2021

About this map

The Tongass National Forest dominates this Alaskan landscape, where the Coast Mountains meet a complex network of glacial drainage. The center of the sheet is marked by the high-elevation Blue Lake, which feeds into the Blue River as it winds southward. This 2021 survey illustrates the primary topographic features of the region, including the prominent Albert Ridge and the Lava Fork waterway. In the southern reaches, the Unuk River cuts through the terrain, a critical corridor for the region's hydrology. The boundary for Wrangell is also indicated, showing the intersection of municipal interests with the preserved wilderness of the national forest. The map captures the remote character of the international border area, with the Usa line visible in the northeastern corner of the quadrangle.
