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, Hell's half acre Arkansas is completely composed of sharp jagged rocks and no vegetation (aside from the few trees that appear in the satellite photo). Hell's half acre Arkansas 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.
A road that led to Hell's half acre Arkansas has since been converted to public land. Another direction in is provided by the first site below, but it is reputedly a treacherous hike. If you decide to go, you might want to check with the Hot Springs officials to verify that this is open to the general public.
