2021 Map of Petersburg D-4 NW

USGS Topo · Published 2021

About this map

The Missionary Range dominates this portion of the Tongass National Forest, where steep maritime peaks rise directly from the tidal waters of Portage Bay. This 2021 survey illustrates a landscape defined by dramatic vertical relief and complex hydrology, from the high summits of Hall Peak and Chipp Peak down to the drainage basins of Goose Creek and Todahl Creek. The coastal interface is marked by distinct navigational landmarks such as Flat Point, Hook Point, and the hazardous Harrington Rock.
