2018 Map of Bradfield Canal B-3 NW
USGS Topo · Published 2018About this map
The Canada United States of America international boundary cuts across the southern portion of this terrain, marking the high-altitude divide between Alaska and British Columbia. This 2018 survey reveals a landscape dominated by the Tongass National Forest, where the complex drainage systems of the Blue River and the W Fork Blue River flow through glaciated valleys. The presence of the Lava Lakes and the Lava Fork in the central part of the quadrangle highlights a unique volcanic and glacial history that has shaped the hydrography of the region. These remote waterways and their surrounding peaks characterize a wilderness where the natural topography dictates the path of the border, providing a precise record of the physical geography of the Ketchikan Gateway Borough at the start of the twenty-first century.
