About this map

Stephens Passage and Holkham Bay dominate the northern coast of this coastal wilderness within the Tongass National Forest. The landscape is defined by its dramatic maritime features, including the hooked protrusion of Wood Spit and the southern reach of Sand Spit, which provide critical reference points for navigation in these Southeast Alaskan waters. The interior remains an undeveloped expanse of steep topography, where the Tongass National Forest boundary protects the pristine maritime forest ecosystem. Grounded in the late twentieth and early twenty-first-century mapping of the Petersburg Borough, the chart details the interface between the high-relief coastal mountains and the surrounding fjords, specifically at the prominent geographic marker of Point Astley.
