About this map

Wrangell Island within the Alexander Archipelago is the focus of this detailed topographical study, which reveals the dense drainage networks and steep terrain of the Tongass National Forest. The landscape is dominated by the watersheds of Pats Creek and McCormick Creek, where the intricate contour lines illustrate the elevation gains typical of Southeast Alaska. Access to the interior is marked by the Zimovia FH 16 corridor and specific paths such as Garnet Trl and the Big Hollow Trl.

The survey highlights the intersection of land and water, particularly along the eastern shoreline near Earl West. From the headwaters of West Fork Creek to the southern reach of Thoms Cr, the map provides an essential reference for understanding the timber and maritime environment of the region. The inclusion of various township and range lines, such as t64s r84e, facilitates precise location tracking for researchers interested in specific forest tracts or historical land use patterns.
