About this map

Coronation Island and its surrounding archipelago dominate this 1948 topographic survey, situated where the Pacific Ocean meets the complex waterways of southeast Alaska. Entirely within the Tongass National Forest, the island is defined by dramatic coastal relief, rising from the waters of Chatham Strait and Sumner Strait to prominent summits like Needle Peak and Windy Peak. The coastline is heavily indented with deep harbors such as Windy Bay and Aats Bay, reflecting a landscape shaped by glacial activity and maritime exposure.

Navigational markers such as the Helm Lt at Helm Pt emphasize the maritime significance of this region during the mid-20th century. To the north and east, the Spanish Islands guard Decision Passage, while a specialized inset details the isolated Hazy Islands including Big Hazy Islet. This survey provides a primary record of the natural topography and coastal features before later environmental changes, focusing on the prominent points like Nation Pt and Aats Pt that guided mariners through these northern reaches.
