2021 Map of Petersburg D-3 SE

About this map

Tongass National Forest dominates this coastal landscape in the Petersburg Borough, where the dramatic rise of the Alexander Archipelago meets the sea. The shoreline is marked by the prominent Frederick Point, providing a navigational landmark for the waters of Frederick. Inland, the terrain reaches sharp elevations at Horn Mtn and the steep Horn Cliffs, which drop toward the coast. Water resources are evident in the managed Cabin Creek Reservoir and the drainage of Crystal Cr and Moonshine Cr. The McDonald Islands sit just offshore, highlighting the maritime character of this region. This modern survey illustrates the conservation-focused land use of Southeast Alaska, showing how infrastructure like the reservoir integrates with the surrounding forest and coastal topography.
