About this map

Tongass National Forest dominates this high-altitude landscape along the international border in Petersburg Borough. The terrain is defined by extreme vertical relief, culminating in the prominent peak of Mt Burkett in the southern portion of the quadrangle. This map documents a strictly natural landscape where the boundary between the Canada United States of America follows the rugged crests of the coastal range. The absence of roads or permanent settlements underscores the wilderness character of this region, which remains a critical area for glaciological study and high-alpine exploration within the larger Alaskan panhandle.
