Thayer Lake South Shelter Cabin

The Thayer Lake South Shelter Cabin is a historic backcountry shelter in the Admiralty Island National Monument, part of the Tongass National Forest in Southeast Alaska. It was one of a number of such facilities built by Civilian Conservation Corps (CCC) on the Admiralty Island Canoe Route between 1933 and 1937. This cabin, a three-sided Adirondack-style log structure with shake walls and roof, was built in 1935, and is located near the southern tip of Thayer Lake, facing a reedy stream blocked by a beaver dam. A portage trail runs nearby.

The cabin was listed on the National Register of Historic Places in 1995.
