Skinwalker tales, like those of El Chupacabra, are not Native to Anglo American Culture of the United States but over the lost few decades have been reported by people of all ethnic backgrounds. In traditional Navajo Culture, the skinwalker, or yenaald looking is a dangerous practitional of witchcraft who wears the skin of various animals, morphing into a coyote, wolf, bear, owl, or whatever other creature strikes it's fancy. Sightings of skinwalkers have been reported by Non Indians since at least the 1960's but have become a subject of greater interest since the publishing of Tony Hillerman's Novel Skinwalkers and the subsequent television movie based on it. Skinwalkers are usually described as half-human monstrosities who run on two legs and do so at extreme speeds.
A flagstaff woman claimed that one night while she was driving across Navajo Reservations land at about 60 MPG, one of these apparent shape-shifters started running along side her car, tapped on the window, then darted in front of her car and disappeared off the road.
A man said that he had a virtually identical experience while driving near Sedona. This type of road side encounter which has also been reported around Winslow and Window Rock, is by far the most commonly reported on record from modern skinwalker account.
Frequently, they are said to let loose a volley of screeching laughter as they torment the motorists. It is hard to say what lies behind the skinwalker phenomenon, because it is very difficult to get good information from those who know the most about it.
There is a strong taboo in the Navajo culture against talking about witchcraft. Do these dangerous mischief makers really prowl the land? Just to be safe, it might do to consider the advise of a Navajo student interviewed in 1977: " If you ever see a skinwalker, just stand up to him. If you show him you are a scared man, he'll kill you. If you stand up to him and show him you are not scared and stare at him, then he will not hurt you!"
