About this map

Gravina Island dominates this portion of the Alexander Archipelago, characterized by a complex coastline of deep inlets and rocky outcrops. The southern tip is marked by Dall Head, a prominent landmark for navigation near the entrance to Nichols Passage. In the northern section, Flat Mtn and Chapin Peak provide significant elevation, with Downdraft Lake tucked between the interior ridges.

Protection of the wilderness is evident through the inclusion of the Tongass National Forest, which covers much of the island's timbered interior. The maritime environment is defined by protected waters like Bostwick Inlet and Dall Bay, while the eastern margin brushes against the Annette Island Reserve. These features reflect the typical southeast Alaskan geography of secluded bays and steep, forested terrain.
