2017 Map of Petersburg D-1 SE
USGS Topo · Published 2017About this map
Shakes Glacier and the Great Glacier dominate this glaciated terrain along the international boundary between Alaska and British Columbia. This high-altitude landscape is part of the Tongass National Forest, where the heavy ice of the Stikine Icefield feeds into Shakes Lake. The map documents the precise placement of the Canada United States of America border as it cuts through the massive ice flows and high ridges of the Wrangell Borough. The topographic detail reveals the dramatic transition from active glacial faces to the proglacial waters below, capturing the state of these receding ice masses in the early 21st century. It is a vital record for understanding the remote borderlands where coastal rainforest ecosystems meet the subarctic ice cap.
