2021 Map of Sumdum B-2 NE

About this map

The international border between the Canada United States of America defines the central axis of this landscape, carving a sharp diagonal through the wilderness of Southeast Alaska. This boundary line separates the interior highlands of British Columbia from the coastal regions of the Tongass National Forest, illustrating the remote and geopolitical character of the Pacific Northwest. The map provides a look at the Public Land Survey System grid as it meets the jagged international line, including sections within t51s r80e, t51s r81e, and t52s r81e. This cartographic record of the Petersburg Borough region highlights the intersection of national administrative boundaries and the natural topography of the Alaska-Canada frontier.
