About this map

Tongass National Forest and the coastal waters of Southeast Alaska define this 1950s survey of the Sumdum area. The map reveals a remote industrial and postal footprint along the deep inlets of Windham Bay and Endicott Arm, including the isolated Windham PO and the Chuck Mining Camp situated near the mouth of the Chuck River. These small outposts reflect the mid-century reliance on maritime transport and mineral extraction in a landscape dominated by tidal flats and steep fjord-like terrain.

The northern reaches of the sheet are characterized by the glacial waters of Tracy Arm and the Tracy Arm-Fords Terror Wilderness, where islands like Sumdum Island and the Bushy Islands sit within the vast Stephens Passage. This record captures the region just as modern wilderness designations were beginning to protect these coastal ecosystems, while still documenting the active mining and mail infrastructure that once connected these inlets to the outside world.
