Anyone try any of these places?
Apparently there is one in Ireland too, or so my mother used to tell us. She claims to have seen it as a child. I'll ask her when I see her next... -- Orelstrigo 22:56, 25 Nov 2004 (UTC)
This entry badly needs a picture.
I agree a picture would be useful, however the phenomenon results from the gradient of the visible horizon relative to the road and the actual motion of the vehicle. So merely by tilting the camera you could "fake" the effect in a picture, moreover the picture would not capture the rolling of the car. All is not lost however, as the phenomenon can also be seen where rivers flow through areas with sloping rock strata. The sloping strata can give the impression the water is flowing up-hill and a photograph capturing the waves and wakes will give a feel for the direction and dynamic aspect of the effect. I have seen such a photograph and need to track it down. Dave C
The one in Ireland is at the Spelga Dam, Co. Down, near to Newcastle. -- HispanoCelt 11:17, Nov 26, 2004 (UTC)
I have seen one of these places in the Smoky Mountians in TN. This place worked by the illusion of the surrondings. This place as a house built on a hillside that was "tilted" compared to the outside.
I'm sure these roads work much the same way. A section of road actually is downhill, but by looking at the surrondings, it would actually look like it was an "uphill" section of road.

Hey, not to nitpick, but isn't Spook Hill in Michigan in Joyfield Township, not Arcadia? Fishal 05:27, 9 Dec 2004 (UTC)
the gravity road redirect isn't working. Can somebody fix this? (i don't know how) Jm51 19:08, 18 Dec 2004 (UTC)
I have experienced this phenomenon at the Magnetic Hill in Ladakh Region in India. Small Cars slowly move upwards. On a plain or downward road in this area, its difficult to drive in higher gear. To drive smoothly we have to change to lower gears...-- Gktambe, 19:52, Dec 25th, 2006.
Haven't been there in a couple years, but a delightful tourist trap. KateRosok 18:30, 1 February 2007 (UTC)
I am doing a report on gravity hills having been to this particular one I do fool alot of people and tell them the story of the school bus that got hit by a train. and the story gose that the kidds spirits from the buss push your car up hill and will stop you from goting over the train tracks. anyway I will be conducting some researh and will share it when I have more information. —The preceding unsigned comment was added by 161.38.223.230 ( talk) 02:13, 9 March 2007 (UTC).
The Wisconsin Wonder Spot, locally known since the 1950's, is to be demolished for a roadway. It is also mentioned in this blog about "retro culture". An article in the mainstream media ( USA Today) increases its notability. -- 205.201.141.146 20:19, 15 June 2007 (UTC)
Is there a term for the same phenomenon when used in more domestic situations? For example, there is a pub in Dudley in the West Midlands of England called The Crooked House. Unsurprisingly the name derives from the fact that mining subsidence has left the building standing at a severe angle [1]. Inside, shelves have been built out of horizontal in order to accentuate the angles of the walls, meaning that a marble rolled along one of the shelves appears to be running uphill relative to horizontal features, when in fact it is rolling gently downhill relative to the building. So, essentially the same effect, but not using a car and a hillside? DWaterson 00:01, 13 September 2007 (UTC)
This one is from my wife and mother-in-law. The mother in law states that this is the main drive through randsburg, ca (butte ave?) and right in front of the church. She swears its a true magnetic hill because my father-in-law brought a large level out to test the lay of the land. Also, she states that you can put the car on either side of the magnetic hill and the car will roll to the middle point at the 'top'.
I'm in Delaware, so I can't confirm this. Sorry! The church in question might be the Santa Barbara Church built in 1904. 68.82.74.196 ( talk) 02:16, 15 February 2008 (UTC)
This article said: External links -Scientific Measuring of Anomalies GPS height differences and pendulum oscillation diff. confirmed uphill And links to a (at least in Germany) known private webpage of two authors of pseudoscientific and rather strange books from Berlin who claim to be physicists. Their story shows no scientific measurings at all. The hand-held pendulum used to measure gravity (pendulum gravimeter), together with a hand-held clock, will never produce a usuable result. Fixed mounted and wind-shielded pendulum gravimeters may have at best a precision of about 0.2%. But (real) gravity anomalities on earth are below that value. And a hand-held (!!!) and not wind-shielded pendulum will give a much more poor precision and will never show any gravity anomality at all. The use of a GPS along a street is a better idea, but vertical precision is unfortunately not very good (perhaps 5 m). Google Earth knows that street via dei laghi and you can drive along that street in Rocca di Papa (italy) using your mouse, and Google Earth will show you for every meter the altitude. A topographical map of the region would also make clear if that street is uphill or downhill. So, there is no evidence for any scientific measuring on that page. The authors also omit to calculate the influences of the latitude (here 41 degrees N) and altitude (aprox. 600 m) on gravity itself. There is no reason for such a link.

Anyone think we should add this to Wikipedia: Unusual articles? —Preceding unsigned comment added by 75.172.44.243 ( talk) 03:34, 17 November 2008 (UTC)
I just can’t get my head round what the point of the distinction being made in the article, where it begins by listing “A gravity hill, also known as a magnetic hill (and sometimes a mystery hill or a gravity road)”, and then goes on to say that Websites devoted to the paranormal also tend to have names like "Haunted Hill", "Magnetic Hill", or "Anti-gravity Hill", as if Gravity Hill was in some way “more scientific” or “less paranormal” than “Anti-Gravity Hill”. It’s fine to say that people call them this, that or the other, and then say that some people have attributed what is in fact an optical illusion to supernatural forces, but the paragraphs as the stand have no point. Is there a recognized body (for geologists, surveyors, engineers or others in the know), who have defined the term “Gravity Hill” (how it occurs, when it should be applied, etc.) over all the other names? Has some handout gone round the paranormal web-sites to say use these terms, but not Gravity Hill? All hills demonstrate gravit at work if you release the handbrake with your car set on the slope; “Anti-Gravity Hill” actually better expresses the illusion, as it implies the apparent counter-intuitive nature of what seems to happen in these areas. The list of names misses out “Electric Brae”, most popularly applied to the hill at Croy in Scotland, but used elsewhere in Scotland for similar phenomena - but you would find it used both in descriptions in publications and on the web, to attribute scientific or non-scientific solutions to the effect. My point is that suggesting that the initial set of names are “good” and the latter set “bad”, from a scientific, non woo-woo angle is both misleading and wrong.

I’ve asked for a citation for the paranormal connection; I’ve seen the claim loads of times in scientific or sceptical sources; never actually in a paranormal one. Has anybody, or is it just a straw man comment? Moonraker12 ( talk) 14:49, 6 August 2010 (UTC)
I have added the list of gravity hills to 'see also' - I know it's in the first section as well, but it isn't very obvious if you just scan. It is the sort of thing that should be in 'see also'. I made this comment because I saw that someone else has already removed it from 'see also'. If there's some reason for not having it twice, I'd say it's better to have it only in 'see also' Chris.let ( talk) 14:58, 28 August 2012 (UTC)
hardly seem a point to having a seperate article that says little more than the description on the list page.. — Preceding unsigned comment added by 132.3.33.78 ( talk) 17:39, 8 July 2014 (UTC)
