The Hasselborg Lake East Shelter Cabin was a historic backcountry shelter in the Admiralty Island National Monument, part of Tongass National Forest in Southeast Alaska. The cabin, of which at best ruins survive today (it was described as being collapsed as long ago as 1985), was a three-sided Adirondack-style log structure, made of peeled logs, and covered with wood shakes. It was located near the mouth of the stream that drains Beaver Lake into Hasselborg Lake. The shelter was built in 1936 as part of a Civilian Conservation Corps works project to create a canoe route across the island.
