Hell's Half Acre
The area of land (allegedly more around one to two acres) is a bit of a mystery to residents in nearby Hot Springs, Arkansas. Despite being completely surrounded by forest and vegetation, this section is completely composed of sharp jagged rocks and no vegetation (aside from the few trees that appear in the satellite photo). The place is reportedly feared by locals and even the hunting dogs and some believe that the devil lurks below. Geologists are said to be baffled and theories range from an extinct volcano (that warms the hot springs in the area) to a vortex that has trapped fallen angels who await their release on the final Day of Judgement.

In the same general area lies a deep black hole. The legend that surrounds it has it as a bottomless hole where a demon has been trapped. Those that pass by night report hearing its groans and shrieks of profanity. As such, people tend to stay away at night.

"Was watching a tv show last night called "Seeing vs. Believing", they were in Hot Springs, off Mill Creek Rd...anyhow, said locals won't go there, especially at night and said that animals won't cross it (they had two coon dogs w/ them that they tried to lead across the rock quarry but the dogs wouldn't have it...they started whining and whimpering....said that birds won't even fly over it..."

"I actually used to live right by it. Anyone considering going there should forget it! Thats why they closed the quarry, 3 people died while digging, and 2 lost their minds. They say a evil spirit lives there. Every person thats went there since has either died or went insane."
