About this map

The Tongass National Forest dominates this section of the Coast Mountains in Southeast Alaska, where glacial activity and heavy precipitation have carved a landscape of high summits and deep valleys. The northern portion of the quadrangle is anchored by Farragut Lake, while the Farragut River winds through the western lowlands, likely serving as a critical drainage for the surrounding icefields and snowmelt.

Prominent high points define the eastern and southern terrain, including Gray Peak and the cluster of Henry Peak, Dana Peak, and Marsh Peak. This 2018 survey illustrates the character of a roadless wilderness area, where natural geography remains the primary feature. The absence of settlements or established roads highlights the extreme isolation of this part of the Petersburg Borough, a region where topographical contours and river systems provide the only markers for navigation and land management.
