2017 Map of Petersburg A-3 NW

About this map

Tongass National Forest encompasses the entirety of this coastal Alaskan landscape, where the waters of the Gulf of Alaska meet a complex network of islands and passages. The archipelago is dominated by the Kashevarof Islands and the Blashke Islands, separated from larger landmasses by the Kashevarof Passage. Topographic detail reveals the steep, wooded terrain of Zarembo Island and Shrubby Island, punctuated by navigational landmarks like Point Nesbitt and the treacherous Nesbitt Reef. The map illustrates a wilderness defined by water, where named channels like Ossipee Channel provide the only thoroughfares through the scattered outcrops. This 2017 survey shows the intricate shoreline of the Wrangell Borough boundary, tracing a maritime environment where isolated features like Bluff Island and Middle Islands remain largely untouched by development.
