The Tongass National Forest dominates the southwestern corner of this survey, which primarily documents the high-altitude interface between the United States and Canada. The map focuses on a segment of the Alaska and British Columbia border, characterized by an Indefinite Boundary that underscores the difficulty of mapping this remote glaciated terrain. High points like Snow Top and Boundary Peak 108 serve as the primary landmarks in a landscape defined by extreme elevation rather than human settlement. This document is part of a larger international effort to define the frontier, based on photogrammetric methods from 1948 aerial photography and field-annotated in 1960. It captures a moment in the mid-century surveying of the North, where topographical precision met the physical reality of the Pacific Northwest's ice fields and summits such as Boundary Peak 106.
