About this map

Tongass National Forest dominates the coastal landscape of this quadrangle, where the intricate shoreline of Pybus Bay meets the open waters of Frederick Sound. The geography is defined by prominent headlands such as False Point Pybus, Square Point, and Point Pybus, which mark the transition from the forested interior to the sea. Offshore, the San Juan Islands and the solitary West Brother Island rise from the sound, illustrating the archipelago character of this maritime wilderness. Farther south, the isolated Round Rock sits within the maritime boundary, serving as a distinct navigational landmark. This survey provides a precise view of the coastal topography and township boundaries as they existed in the early 21st century, revealing the primitive, undeveloped nature of these protected lands within the Unorganized Borough.
