For decades, a mysterious pair of spirits—a horse and its rider—have been said to haunt a long-vanished stretch of train track that once cut through the northern expanse of the Great Plains. Some said they were little more than a trick of fog in the moonlight, but that was before human remains were found nearby. Figment or phantom, it’s an excellent piece of folklore from the Canadian west, with ties to a community and a history that’s in danger of being forgotten.
