About this map

Glass Peninsula and the eastern coast of Admiralty Island dominate this coastal survey, which documents the maritime geography of Southeast Alaska in the mid-20th century. The land within this part of the Tongass National Forest is defined by sharp topographic shifts, from the high ridges of Yeek-Sha Mtn to the distinct formation of The Stone Wall. The waters of Stephens Passage and Seymour Canal separate the island masses, providing a look at the intricate shoreline before modern navigational aids were digitized.

A notable portion of the peninsula is designated as a Lighthouse Reserve, signaling the importance of these points for coastal navigation. Named landmarks like Pt Lookout and Midway Pt served as essential reference points for vessels moving through these corridors. The absence of roads or trails emphasizes the isolation of this wilderness during the 1950s, where movement was dictated entirely by the tides and the sea.
