Discovered in the 1940s, this site on Branciforte Drive in Santa Cruz just might be the most well-known "mystery spot" in the U.S. Tour guides walk visitors through the "Mystery Shack" that stands on this spot and demonstrate the many weird effects that seem to take place there. Balls roll uphill, brooms stand on end at odd angles, people's heights seem to change as they walk about, among other weird effects of perspective and gravity. Even the trees in the area do not stand straight. Some visitors actually feel faint within the shack.
