2021 Map of Petersburg D-2 SW

About this map

Tongass National Forest dominates this coastal landscape in the Petersburg Borough, where the dramatic rise of the Horn Cliffs meets the protected waters of Frederick Sound. The map reveals a wilderness shaped by significant drainage systems, including the Muddy River and North Blind River which flow through the northern reaches. High-altitude landmarks like Thunder Mtn overlook a complex network of smaller tributaries such as Bussy Cr and Moonshine Cr. While largely roadless, the presence of the Muddy River Trl indicates established routes through the dense forest and mountain terrain. This survey provides a clear view of the topography before contemporary changes, documenting the precise interfaces of Alaskan coastline and interior peaks.
