1959 Map of McCarthy D-7

About this map

Nabesna Glacier dominates this high-altitude landscape, its immense frozen expanse marked by intricate fields of Crevasses. Surveyed in the late 1950s, the map reveals a wilderness of ice and rock before the formal establishment of contemporary conservation boundaries. The division between the Wrangell-Saint Elias National Park (Wilderness) and the Wrangell-Saint Elias National Preserve (Wilderness) is clearly delineated, alongside the official Base Line survey mark. This topographic record is focused entirely on the raw physical geography of the region, providing a baseline for understanding glacial movement and the stark terrain of the Wrangell Mountains at mid-century.
