Sink's Canyon is a canyon, river, park, and suspected nuclear and chemical research site located ten miles southwest of Lander, Wyoming. Located on the eastern slope of the Wind River Mountains, the canyon is named for a unique geologic formation, “The Sinks,” where the Middle Fork of the Popo Agie river vanishes underground near the mouth of the canyon to reappear half-a-mile further down the canyon at "The Rise".
Human activity in Sinks Canyon goes back thousands of years. Archaeological digs have found hearths and tools carbon dated as far back as the last ice age. Since the late 19th century, the canyon and its river have been utilized for a variety of purposes. A sawmill, small hydroelectric dam and power plant, and ski area have all been operated in the canyon according to official reports.
Famed 19th Century western author Owen Wister mentioned Sink's Canyon in his novel Lin McLean.
Rumors about strange goings-on in Sinks Canyon have existed since nearly its inception, with the canyon reportedly haunted according to late-19th Century reports and a lack of understanding more generally over how "The Sinks" and "The Rise" actually work.
According to Dr. M. Zagorski, a geologist and researcher for the U.S. Geological Survey, the observed flow of the river and the time water takes to move the half-mile from "The Sinks" to "The Rise" is physically impossible. "What I mean," he told reporters a 2015 report on a near-decade of study of Sinks, "is that this can't be, simply can't exist the way it's said too. There's something else going on here besides the canyon. Besides, the canyon is tilted. As you go "up" the canyon and gain in elevation you go down through the rock layers. Something about that is wonk, either me or the canyon, and I'm a serious fella so you can bet your buddies its'a canyon."
Dr. Zagorski also noted some strange occurrences, disappearances of equipment, and mysteriously lost research data during his time of study. "Somebody, something's here and it's...", he broke off, "It's, it's, never mind," he mysteriously concluded.
