Researchers Say Gardom’s Edge Monolith Is Astronomical Marker
A team of researchers from the Nottingham Trent University has suggested that a 4000-year-old unique triangular shaped monolith, known as the Gardom’s Edge monolith, was aligned to be an astronomical marker.
The 2.2 meter high monolith, located in the Peak District National Park near Manchester, UK, has a striking, right-angled triangular shape that slants up towards geographic south. The orientation and inclination of the slope is aligned to the altitude of the Sun at mid-summer.
The team believes that the monolith was set in place to give symbolic meaning to the location through the changing seasonal illuminations. The findings will be published in the conference proceedings of SEAC 2011.
The researchers have conducted a microtopography survey of the surface surrounding the monolith. The findings indicate the presence of packing stones around the base of the monolith, evidence that it was placed carefully in position. They have also carried out 3-D modeling of illumination of the stone through the seasons, adapting for changes in the Earth’s tilt to the ecliptic plane over four millennia.
The landscape surrounding the stone harbors many ancient monuments such as Bronze Age roundhouses, a late Neolithic enclosure, and other traces of a long lasting human occupation.
The researchers believe that the stone is also late Neolithic, set in place around 2000 BC.
“Given the sensitivity of the site, we can’t probe under the surface of the soil,” explained Dr. Daniel Brown, a lead author and an astronomy lecturer at the Nottingham Trent University. “However, through our survey, we have found a higher density of packing stones on one side, supporting the case that the stone has been orientated intentionally.”
The 3-D modeling shows that during the winter half-year, the slanted side of the stone would remain in permanent shadow, during most of the summer half-year it would only be illuminated during the morning and afternoon, and close to midsummer it would be illuminated all day. The team is currently backing up the modeling work by gathering contemporary photographic evidence of the stone.
“The stone would have been an ideal marker for a social arena for seasonal gatherings,” Dr. Brown said. “It’s not a sundial in the sense that people would have used it to determine an exact time. We think that it was set in position to give a symbolic meaning to its location, a bit like the way that some religious buildings are aligned in a specific direction for symbolic reasons.”
The researchers hope that the new evidence will support the case for a wider archaeological survey of the site.
“The use of shadow casting in monuments of this period is quite rare in the British Isles,” Dr. Brown concluded. “But there are some examples including New Grange, Ireland, and some Clava cairns in the north-east of Scotland that have been proposed to include the intentional use of shadows. Both are associated to burial sites using the symbolism of a cyclic light and shadow display to represent eternity. Given the proximity of the Neolithic enclosure and possible ritual importance of this site, the Gardom’s Edge monolith could be another such example.”
It's a bit different from the one featured in Stanley Kubrick's film 2001 A Space Odyssey ... but it is quite interesting nonetheless

What does it measure in Courics ?
Would that be pointing South + or - how many degrees?
Would that be in 2000 BC or 2012?
With all of the technology available today why were they unable to find the chamber where Jim Kirk awoke and groggily made his way to the surface. Loved that Indian chick.
The article referenced the stone being put in place about 4000 years ago, or around 2000 B.C.
I cannot elaborate about the direction or degree of angle ...
Oh yeah ... I remember that one. An amnesiac Kirk knocks up a Pochahontas lookalike and earns the wrath of the jealous medicine man. Medicine man injures Kirk and proclaims to all “Behold the god who bleeds!”
What a memory...you remembered a dramatic moment, line and all. I was focused on the lovely lady.
But, I was in college and that’s pretty much what I did all the time.
It looks more interesting than Kubrick’s monolith.
It looks like a rock to me. If that is a monolith then there are thousands around here. It’s a rock :P

As shown, the sun, at the summer solstice was a little more than 0.4 degrees higher in those days than now. (And ~0.4 lower at the winter solstice.) The variation in the height of the noon day sun changes very little from day to day near the soltice, less than 0.01 degrees per day the day before and after, so this instrument would only have yeilded, at best, a vary crude approximation of the date of the solstice.
Or were the other rocks broken after they fell off from being balanced on the “nose”?
Has anyone accounted for the freeze-thaw cycle or settling of a 4000 y.o. stone?
