1959 Map of McCarthy B-1

USGS Topo · Published 1981

About this map

Mount Bear dominates the southern reaches of this high-altitude survey, standing as a massive sentinel over a landscape defined by glacial activity. This remote stretch of the Saint Elias Mountains is characterized by the expansive Klutlan Glacier, which flows eastward across the northern portion of the map. The terrain is marked by numerous crevasses, illustrating the dynamic and treacherous nature of the ice fields in the late 1950s. The map serves as a primary record of the international boundary, tracing the United States Canada border along the 141st meridian, where it meets the Alaska Yukon line. The absence of roads or established trails highlights the extreme isolation of this environment at the time of the 1957 aerial photography and subsequent 1959 field annotation.
