Reality TV is a combination of an interesting idea and non-actors who will illustrate it as long as they don't have to memorize a script. When I heard about one taking place in Portlock, Alaska, I had to see if it has any basis in reality whatsoever. The history of Portlock is certainly mysterious. The town on the Kenai Peninsula grew up around a salmon cannery in the early 20th century. But it was completely abandoned in 1950.
Around the 1940s, it was reported that several Dall sheep hunters had disappeared in the hills outside Portlock; it was also stated in a 1973 article from the Anchorage Daily News that dismembered bodies of some of the missing had washed ashore in the lagoon. These events led the residents of the community to flee en masse, and the town's post office officially closed between 1950 and 1951. Many villagers blamed the unexplained deaths and disappearances on a Bigfoot-like creature referred to locally as Nantinaq.
The residents of Portlock moved to Nanwalek and Port Graham. In recent years, some people in Nanwalek have raised the possibility of re-establishing a community in Portlock. The story was certainly ripe for the reality show treatment. Discovery+ is streaming a series called Alaskan Killer Bigfoot (subscription required) that follows a group of guys going to Portlock to check it out.
