2021 Map of Sumdum A-3 NW

About this map

Tongass National Forest dominates the interior of this coastal Alaskan landscape, where the Farragut River carves a deep valley toward the northwest corner of the quadrangle. The river’s drainage is fed by several high-elevation features, including Farragut Lake and the precipitous slopes of the Coast Mountains. This 2021 survey reveals a primitive and high-relief terrain where prominent summits such as Gray Peak, Henry Peak, and Dana Peak provide essential orientation markers for navigators and surveyors. In the southeastern reaches, Marsh Peak stands as a final sentinel before the land gives way to further glacial valleys. The map illustrates a landscape shaped by hydrology and elevation, showing the intricate relationship between the river system and the massive mountain ranges that define the Alaska-Canada borderlands.
