1959 Map of McCarthy A-1

About this map

Anderson Glacier and Tittmann Glacier dominate this remote Alaskan landscape, where the ice flows converge near the international border. Mapped in the late 1950s by the Usgs and the International Boundary Commission, this survey captures the frozen divide at Alaska Yukon. The high-altitude terrain is defined by massive peaks, including Mount Anderson and Mount Tittmann, which rise above heavily crevassed ice fields. The southern portion of the quadrangle is occupied by the broad expanse of the Chitina Glacier. This map provides a technical record of glacial extent and the United States Canada boundary line before modern satellite tracking, showing the distribution of crevasses and rock outcroppings near Mount George.
