1951 Map of Sumdum C-6

About this map

Glass Peninsula and the eastern coast of Admiralty Island dominate this mid-century coastal survey. Separated by the waters of Seymour Canal, the landscape is defined by its deep inlets and maritime landmarks. The southern tip of the peninsula is notably designated as the Lighthouse Reserve, indicating its importance for regional navigation through Stephens Passage. This specific edition, though field-annotated in 1951, incorporates hydrographic data reaching back to 1889 surveys, providing a layered perspective of the shoreline.
