2021 Map of Sumdum C-5 NE

About this map

Tongass National Forest dominates this coastal landscape in the Petersburg Borough, where the glacial waters of Endicott Arm carve through the terrain. The map highlights the maritime geography of the region, specifically focusing on the navigable waters and the hazardous outcroppings that define this stretch of the Alaska coast. Inland, the topography rises sharply from the shoreline, with contours marking the steep ascent into the protected forest lands. Features like Sumdum Island and the Bushy Islands sit at the mouth of smaller inlets, providing essential landmarks for coastal navigation. On the western shore, Sanford Cove and the prominent Rock Point represent the interface between the deep fjord-like waters and the dense, protected wilderness. The survey documents the area as it appeared in 2021, capturing the precise shoreline and elevation data of this remote maritime environment.
