About this map

Prince of Wales Island is dominated by the intricate shorelines and tidal systems of the Tongass National Forest in this 2017 survey. The landscape is defined by its deep saltwater inlets, most notably the West Arm Moira Sound and South Arm Moira Sound, which carve deep into the mountainous terrain. These waterways were essential for coastal navigation and subsistence in this part of Alaska, with protected anchorages like Frederick Cove providing refuge from the open waters of the Gulf of Alaska.

Smaller tidal features such as Biscuit Lagoon and the passage known as The Saitchuck indicate a complex littoral environment where land and sea meet. Inland, the topography rises sharply from sea level to over 2,000 feet, punctuated by landmarks like Biscuit Knob. This map records the natural drainage patterns of short, steep coastal streams like Perkins Creek before they discharge into the Pacific.
