About this map

Etolin Island and Prince of Wales Island dominate this coastal survey, where the intricate waterways of Southeast Alaska's Alexander Archipelago are meticulously documented. The map highlights a complex maritime environment within the Tongass National Forest, centered around Kashevarof Passage and the broad expanse of Clarence Strait. Landforms range from the larger Zarembo Island to small clusters like the Blashke Islands and Screen Islands, illustrating the navigational challenges of these fjords and channels.

Evidence of historical industrial activity is anchored at Cannery (Aband) on Lake Bay, suggesting the transient nature of the region's early 20th-century salmon packing industry. Coastal landmarks such as Coffman Cove and Steamer Knoll provide fixed points for understanding the early maritime development of this region. The absence of roads or established trails throughout the islands emphasizes the total dependence on marine transport through Whale Passage and Ossipee Channel during this era.
