The Eagle Ranger Station, also known as the Eagle Guard Station and presently known as the Sol Duc Ranger Station, is a complex of three buildings built in the 1930s in what would become Olympic National Park. The primary structures were built by the U.S. Forest Service in what was at the time the Olympic National Forest., While the main residence was built by the USFS, the generating plant and landscaping were built by the National Park Service using labor provided by the Civilian Conservation Corps.
