1959 Map of Nabesna A-6

USGS Topo · Published 1965

About this map

Mt Jarvis dominates the southern reaches of this high-altitude landscape, where vast ice fields and glacial movements define the geography of the late 1950s. The topographic detail captures the massive Copper Glacier and Jacksina Glacier, highlighting the extensive crevasses that mark these frozen rivers. These glaciers feed into the headwaters of the Copper River, illustrating the fundamental hydrological connection between the mountain summits and the valley floor. To the northwest, West Glacier and the drainage of Tumble Creek further emphasize the glacial-dominated terrain. This survey, based on 1957 aerial photography, provides a literal map of a shifting ice-bound wilderness before significant modern climatic shifts, preserving the exact contours of the peaks and the precise margins of the ice as they stood mid-century.
