Wilderness Atlas publishes a centroid and an acreage for each unit, not a boundary line. Distance here is measured to a circle of the same area drawn around that centroid, so treat it as roughly right rather than surveyed.

Name, location, type and dates come from the National Register office's spreadsheet of listed properties, because the Park Service's spatial data does not carry this listing. The map point comes from Wikidata. Construction date, architect, style, photograph and encyclopedia link come from Wikidata and Wikimedia Commons, matched on reference number 66000217. Nothing here is transcribed by hand. The nomination form and photographs ↗ at NPGallery are the original nomination as filed with the National Park Service, and the form is often the best description of the place.
