2021 Map of Sumdum A-1 NW

About this map

Mt Burkett dominates the high-altitude landscape of the Coast Mountains, marking a prominent point in this glaciated frontier. This 2021 topographic survey focuses on the international boundary where Canada meets the United States, with much of the American side protected within the Tongass National Forest. The map detail captures a terrain of extreme relief and ice, defined by the Public Land Survey System grids of t53s r83e and t54s r82e. As part of the Alaska-Petersburg Borough area, the sheet illustrates the sheer isolation of this borderland, where traditional human infrastructure is absent in favor of natural features and precisely defined political boundaries.
