Tongass National Forest covers the southern portion of this high-latitude survey, marking a significant transition where the United States meets Canada. The landscape is dominated by extreme elevation and glacial terrain, with the international boundary cutting directly across mountain ridges and ice fields. Snow Top stands as a prominent landmark in the southwestern quadrant, overlooking the high-altitude divide. The absence of roads or permanent settlements reflects the strictly protected and inaccessible nature of the Haines Borough panhandle in this era, where the mapping focuses entirely on natural topography and geopolitical lines rather than human infrastructure.
