1959 Map of McCarthy B-1

About this map

Klutlan Glacier dominates the northern portion of this high-altitude landscape, its expansive ice field marked by numerous crevasses as it flows eastward. This mid-century survey, based on 1957 aerial photography and 1959 field annotations, documents the glaciated terrain along the international border. The elevation culminates in the south at Mount Bear, a prominent peak that anchors the rugged topography of the Saint Elias Mountains. The map precisely illustrates the United States Canada boundary, which also serves as the line between Alaska Yukon. This document provides researchers with a record of glacial extent and alpine morphology before late-century shifts, offering a baseline for studying this remote borderland where no roads or trails existed at the time of the survey.
