Level Islands sit at the center of this coastal survey, where the waters of the Gulf of Alaska meet the sheltered passage of Sumner Strait. These small landmasses, including Big Level Island and Little Level Island, are surrounded by navigational hazards such as White Rock and Vichnefski Rock. The map illustrates the complex shoreline of southeast Alaska's Alexander Archipelago, featuring the southern edge of Kupreanof Island and the northern tip of Zarembo Island.
