About this map

Revillagigedo Island and Gravina Island dominate this coastal survey, separated by the vital waterway of the Tongass Narrows. In the early 1990s, the city of Ketchikan appears as a dense grid of streets along the eastern shore, supported by maritime infrastructure including a Heliport and a Seaplane Base. Across the narrows on Gravina Island, the Ketchikan International Airport occupies the shoreline at Charcoal Point, illustrating the unique geographic separation between the town and its primary airfield.

The interior of the islands is defined by high peaks and ridges within the Tongass National Forest, such as California Ridge and Dall Ridge. The landscape is etched with named summits like Sullivan Mountain and Nipple Mountain, while drainage systems like Bostwick Creek and Government Creek flow toward Bostwick Inlet and Blank Inlet. This map provides a detailed view of the interaction between the industrial waterfront of Ketchikan and the surrounding timberlands and waterways.
