2018 Map of Bradfield Canal A-2 NW

About this map

Tongass National Forest dominates this high-latitude terrain along the international boundary between the United States and Canada. The landscape is defined by the heavy glaciated reaches of the Coast Mountains, where elevation and ice fields dictate the flow of water. The Leduc River winds through the southeastern portion of the quadrangle, carving a deep valley through the mountainous interior. In the northern section, Smith Lake sits near the base of slopes rising toward Mt Blaine, which marks a significant high point along the border. This 2018 survey provides an exact look at the contemporary glacial extent and drainage patterns in a region where few permanent settlements exist, focusing instead on the dramatic physical geography of the Canada United States of America border region.
