This is a madcap story about a tract of land which is topologically folded through a shamanic incantation. Contains descriptions of some physical effects but explicitly states that the topological defect exists only in the human mind (photographs of the area show no anomaly). It should be compared to Baxter's "A Pacific Mystery", which talks about a similar topological curiosity, albeit one that is physical in nature. Might also be comparable superficially to Priest's 'Inverted World'. It is an enjoyable tall-tale if you leave your grain of salt aside.

I've read several other stories by this author and this is one of my favorites.
