Hetta Inlet is a deep embayment in the southwestern coast of Prince of Wales Island in the U.S. state of Alaska.
The white crystalline limestone of the Wales series, striking nearly north and south, is the predominant country rock of Hetta Inlet.
The igneous rocks, so far as determined from the small collection made, include gabbros, diorites, amphibolites, diabases, and pyroxene-syenites.
[1] The inlet is bordered on the west by lands of the Tongass National Forest, which are included in the 13,720 acres (5,550 ha) Hydaburg Roadless Area.
Freight was delivered by small steamers from Ketchikan, and also by Puget Sound vessels, which occasionally called at the camps along the inlet.
