1959 Map of McCarthy A-1

About this map

The Alaska Yukon boundary defines the eastern edge of this high-altitude landscape, where the United States Canada border intersects an environment dominated by massive ice fields. At the center of the survey, the Tittmann Glacier and Anderson Glacier flow through deep valleys, flanked by their respective peaks, Mount Tittmann and Mount Anderson. To the south, the Chitina Glacier spans the width of the valley, receiving ice from smaller, animal-named tributaries including Ram Glacier, Lamb Glacier, and Ewe Glacier. This map captures a strictly glaciated wilderness as it was recorded in the late 1950s, showing no roads, trails, or human settlements. The intricate contour work illustrates the convergence of these frozen rivers and the sharp relief of landmarks like Mount George.
