2021 Map of Ketchikan A-4 NE

USGS Topo · Published 2021

About this map

Tongass National Forest dominates this coastal Alaskan landscape, where the waters of the Behm Canal separate rugged mountainous terrain from the intricate shoreline of Revillagigedo Island. The geography is defined by sharp elevation changes, rising from the canal to the heights of Behm Mtn and Backbone Mtn. This survey captures a wild stretch of the Ketchikan Gateway Borough characterized by deep inlets and prominent coastal landmarks such as Point Sykes, Roe Point, and Alava Point. Small freshwater features like Sykes Lake and Sykes Creek drain the timbered interior, while Alava Bay provides a sheltered cove behind Bass Point. The presence of Black Island in the southern reach of the canal illustrates the complex archipelago nature of this region, providing essential context for those studying the maritime and natural history of the Alexander Archipelago.
