The location is known for its history, including being an Indian reservation. Over time, a number of witnesses, including several police officers claimed to have seen a paranormal entity nicknamed “The Tall Man”. This long armed figure, has been compared to that of “Slender Man”. They are tall brooding figures, reaching heights upwards of around 7 to 8 feet.
This Tall Man figure, has allegedly influenced the deaths of teenagers living in the Sioux Falls area of South Dakota. One elderly woman described Walking Sam (The Tall Man) as a big man wearing a tall hat.
The figure emerged around a reservation, causing teens to fall into a mental state of depression ultimately ending their lives. Within the Pine Ridge reservation, there have been nine people who have died by their own hand here ages 12 to 24. The location is covered with vast grasslands and dusty plateaus where the wind blows.
