Gravity Hills

As a young child I occasionally heard stories about a place you could go where your car (out of gear, brakes off) would be pulled up a hill, as if by some invisible power. This place was called "Gravity Hill" and it was somewhere in Baltimore County, Maryland.

In January, 1980, the Enigma Project managed to rediscover Gravity Hill as being in northwestern Baltimore County along a public road which ran through the Soldier's Delight environmental area. Sure enough, as we experienced firsthand, if you positioned your car at the bottom of the apparent rise on Gravity Hill, and left it in neutral with the brake off, it would very decidedly roll up the road--as if in defiance of gravitation--for about a tenth of a mile before stopping. To naked eyes, at least, the slight grade in the road did go up, and with it so did vehicles positioned on its surface. These circumstances clearly presented a dilemma which the Enigma Project felt obligated to explore.

Fortunately, one of the Enigma Project's local associates, Mike Gilbert, was a surveyor by profession and we wasted little time in getting him to assess the anomaly. Mike examined the road with a transit and carefully marked it off, making notes all the while. When finished he presented us with a drawing of his survey, the results of which were quite surprising. The road's slight "rise" was, in fact, a "fall." Yes, contrary to what the eye perceived, Gravity Hill was actually a decline. Summarily, we learned that it was not a place where Nature's laws go awry, but rather, a unique location for an optical illusion. Evidently, the lay of the land, the sway of the trees, and so forth set the stage for an unusual, though not mysterious, error in visual perception. Interestingly, at least three additional gravity/magnetic hill locations in Maryland (they have not been thoroughly investigated) have come to the attention of the Enigma Project and we have heard about other locations throughout the U.S., Canada and abroad.
