1960 Map of Sumdum A-1

About this map

Le Conte Glacier dominates the southern reaches of this high-altitude survey, illustrating the frozen landscape of the Alaska-Canada boundary during the mid-twentieth century. The international border is defined by prominent peaks including Kates Needle and Mount T, which mark the line between the Alaska territory and British Columbia. The topography is characterized by massive ice fields and dangerous Crevasses, recorded through photogrammetric methods from aerial photography taken in 1948 and 1961. This document serves as a specialized study of the Stikine Icecap region, focusing on the glaciated peaks like Mount Burkett where traditional settlement and road networks are entirely absent. The work was overseen by the International Boundary Commission, reflecting the technical cooperation required to map this extreme environment.
