2017 Map of Petersburg D-3 NW

About this map

Tongass National Forest dominates this coastal Alaska landscape, where the tides of Frederick Sound meet a shoreline of points and inlets. The map highlights the rugged maritime geography of the Point Agassiz Peninsula, stretching between Thomas Bay to the north and the open sound to the south. Land-based navigation is represented by the Colp Lake Trail and the Point Agassiz Connection, providing rare inland access through the dense forest. Notable coastal landmarks such as Beacon Point and Wood Point flank the peninsula, while the isolated Sukoi Islets sit offshore within the sound. This 2017 survey reflects the remote, wilderness-focused character of the region, where activity is concentrated along the waterline and a few established forest routes like Fivemile Cr.
