"There are dozens of mystery spots to be found around the U.S., and many more gravity hills - places where gravity itself seems to be warped. Our perceptions of up, down, straight and crooked are confused by what some say are powerful gravitational anomalies and dizzying magnetic vortexes. Is that the case, or are our senses being fooled by clever man-made and natural optical illusions?
Here are just some of the more well-known locations:
The Mystery Spot - Santa Cruz, Ca.
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.
Spook Hill - Lake Wales, Fl.
Located between Orlando and Tampa, this stretch of road off Hwy. 27 is said to have gravity-defying effects on cars. The phenomenon on the sloping road is so well known that there is a sign on the roadside explaining its legend:
"Many years ago, an Indian village on Lake Wales was plagued by raids of a huge gator. The chief, a great warrior, killed the gator in a battle... The chief war buried on the north side. Pioneer mail riders first discovered their horses laboring down hill, thus naming it 'Spook Hill.' When the road was paved, cars coasted uphill. Is this the gator seeking revenge, or the chief still trying to protect his land."
The story is local folklore, obviously, but drivers do attest that when they stop their cars at a certain spot and shift their transmissions into neutral, the cars do seem to roll up the incline of the road.
The Oregon Vortex - Gold Hill, Or.
Some kind of magnetic vortex - a spherical field of force, half above the ground and half below - is said to be responsible for the peculiar effects experienced at this site's House of Mystery. Those who visit the spot, it is claimed, cannot stand erect anywhere within the vortex, but are always inclined toward magnetic north. Distortions in perceived perspective are also affected, giving the impression, in some spots, that as a person approaches you he or she becomes shorter. There are other weird effects as well.
Gravity Hill - Bedford County, Pa.
It's a place where gravity goes haywire, says one article about this hill near New Paris, Pa. A "GH" spray-painted on the road tells you when you've found the spot where you can stop your car, shift it into neutral, then sit in amazement as it seems to slowly begin to roll uphill. If you're still in doubt, you can do as other experimenters have done and pour water on the road - and watch as it flows uphill."
