Lost Creek Wilderness earned its name for a particular creek in Colorado that has a pesky habit of disappearing at various times during a year. A part of that is it’s largely fed by snowmelt, and once the spring thaw passes, its supply of water dries up literally. Another part of the reason it seems to “disappear” is: portions of the creek flow underground, emerging at various points downstream, which adds to the illusion of it being lost. This region was one of the last refuges of the endangered American Bison, which roamed the valley up until the early 1980s. To protect the dwindling population, the state of Colorado officially established the region as Lost Creek Wilderness in 1980 to protect the herd’s territory. Unfortunately, the bison reached a point where it could not support its population, and they were removed from the area in the 1990s. Lost Creek Wilderness gained its 15-minutes of fame when it was used as a location in a popular television show, Supernatural, in its first season.
