The international boundary between Canada and the United States of America cuts diagonally through this high-altitude landscape in the Coast Mountains. This survey documents a wilderness dominated by ice and rock, where the Baird Glacier flows through the northern reaches of the Tongass National Forest. Significant peaks like Mt Burkett define the local topography, which is largely comprised of federal forest lands and rugged alpine terrain. The map provides a clear visualization of the township and range survey lines, including t53s r83e and t54s r82e, as they interact with the international border at the edge of British Columbia.
