Yesterday I took a walk out to Spoolhenge. It is one of the few local attractions.
The main axis of Spoolhenge is aligned northeast-southwest, and while early research assumed this was an inaccurate alignment on summer solstice horizon sunrise, a far more credible interpretation is that standing on the right hand side of the Heel Spool and looking between the upright pillars of the grand trilithon the monument offers an accurate alignment on the winter solstice sunset. In short, this is how we accurately determine the seasons down here. So I went out to check, and sure enough, the sun is about to set and it will get dark soon.
Some people insists, that these are just a bunch of spools, waiting to be sent back to McMurdo.
