The Lake Guerin East Shelter Cabin is a historic backcountry shelter in the Admiralty Island National Monument, part of the Tongass National Forest in Southeast Alaska. It is 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. As reported in 1995, only remnants of the cabin remain at the east of Lake Guerin, near a portage trail leading to Hasselborg Lake.
