1960 Map of Atlin A-7

About this map

Boundary peaks along the international border between the United States and Canada define this remote mountainous landscape in the Alaska-Haines Borough. Recorded by the International Boundary Commission, this survey captures the high-altitude terrain where the line between British Columbia and Alaska is marked by a series of prominent summits, including Mt Hislop, Mt Poletica, and Mt Service. The topography is dominated by glacial activity, specifically noted by the presence of Crevasses in the southern portion of the quadrangle. As a map without roads or trails, it emphasizes the raw physical geography of the region at the time of the 1960 field annotation, showing the primary importance of natural landmarks in defining the frontier during the mid-20th century.
