Parts of several heavily forested islands that constitute the Alaskan panhandle are visible in this photograph. Snowcapped peaks and ridge lines appear in some of the higher elevations of southward-pointing Baranof Island. Kuiu Island and Kupreanof Island are covered by clouds. Frederick Sound extends eastward from north-south-oriented Chatham Strait, which borders the eastern shore of Baranof Island. Both the sound and the strait are part of the Inside Passage, a sheltered waterway that operates from Seattle, Washington, to Skagway, Alaska. A section of Stephens Passage, an alternate route of the Inside Passage, is visible along the eastern coast of Admiralty Island.
