1959 Map of Cordova D-1

About this map

Wernicke Glacier dominates the southern reaches of this landscape, a massive ice field feeding the Wernicke River as it flows toward the Chugach National Forest. Based on aerial photography from the 1950s, the map documents a transition from the glacier's expanse to the deep cut of Threemile Canyon along the Bremner River in the north. The drainage patterns of Eagle Creek and the South Fork define the interior terrain, which is now protected as part of the Wrangell-Saint Elias National Park and the Wrangell-Saint Elias Wilderness. This survey reflects the region's topography before the formal establishment of contemporary wilderness boundaries, capturing the untouched glacial and riverine systems of the Alaska interior.
