Patrol Cabin, St. Andrew's Creek
The St. Andrews Patrol Cabin was built by the National Park Service in 1922 as part of a network of stations near the boundaries of Mount Rainier National Park for rangers on patrol. The one-room log structure stands on the Wonderland Trail that circumnavigates Mount Rainier. The exterior of the cabin features a porch to the front. The interior is finished with varnished logs and tongue and groove flooring.[2] The cabin was placed on the National Register of Historic Places on March 13, 1991.
