About this map

Peril Strait serves as the central maritime artery in this 2017 survey, dividing the coastlines of Chichagof Island and Baranof Island. The complex hydrography of the region is defined by tight navigable passages like Sergius Narrows and Sergius Channel, where small islands and hazardous rocks such as Midway Rock and Grasstop Rock emerge from the tidal waters. Much of the land is preserved within the Tongass National Forest, showing a landscape dominated by steep elevations and sheltered inlets.

Maritime history is etched into the named points and coves, including Schulze Cove and Deep Bay. The map provides detailed bathymetry and shoreline data for sites like Liesnoi Island and Bear-Bay Island, which sit at the confluence of several channels. These features indicate a terrain where travel and survival have historically depended on an intimate knowledge of the currents and shoals, from Liesnoi Shoal to the sheltered waters of Suloia Bay.
