USGS Topo · Published 2021About this map
The waters of the Revillagigedo Channel dominate this maritime survey of the Alaska coastline within the Tongass National Forest. This southern coastal environment is defined by its series of navigation hazards and rocky outcroppings that line the passage toward the open sea. Numerous named rocks and islets such as Snail Rock, Black Rock, and Indian Rock provide essential landmarks for local mariners and those tracing historical shipping routes through the Inside Passage.
