About this map

Etolin Island dominates the southeastern portion of this coastal survey, where the dense canopy of the Tongass National Forest meets the fractured shoreline of Southeast Alaska. The map traces the intricate maritime geography of the Stikine Strait and the open waters of the Gulf of Alaska, punctuated by hazards such as Mariposa Rock and Key Reef. Notable inlets like Steamer Bay and Kindergarten Bay carve into the mountainous terrain, providing natural sheltered anchorages away from the exposed straits. Smaller landmasses including McIver Island, Observation Island, and Independence Island flank the primary coast, while Steamer Knoll rises as a prominent landmark near the southern boundary. This cartographic study illustrates the isolation of the Alaskan panhandle, where transport and industry are inextricably tied to the deep-water channels and rugged island topography.
