Your opinions - possible wedge tomb?

14-09-2012 11:08am#1Posted on this somewhere else (I think).
This alignment of heavy slabs is in the Wicklow uplands.
Is it a natural formation caused by tree fall like this?
The orientation ticks the box (broadly E/W - 240º to be precise) - this could be a consequence of prevailing wind direction, tree fall, and uprooted slabs. The plantation floor is littered with similar slabs.
There is no sign of a septal slab.
Not visible in the picture above is evidence of excavation in the floor of the alignment (not recent). It is between the megaliths on the right, and behind the trunk in the foreground.
Why or when this dig occurred, I do not know, but wasn't there an old Irish tradition of flattening the floor, and offering milk to the deities in places like this?
It's difficult to determine if the indentations in the picture below are natural or not. If man made, what purpose might they have served?
I should mention that mining has a long history in the district, although this particular feature is outside the mineral rich zone.
The association between copper exploitation and wedge tombs, might weigh in here.
Within an area of around 7-800m, there are remains of various, small scale 'trial' workings, and a possible early (tbc) adit. It is likely that red ochre was exploited close by in the C.17th, and possible medieval iron exploitation.
All in all, a busy, and interesting place!

Here's an embarrassingly bad plan.This reminds me of a similar site I reported to the relavent authority (Dúchas back then), a number of years back. The site in question was on the Dublin side of the mountains. I never followed it up however.
Did you get overall dimensions? Can be handy in doing a morphology...

It's difficult to see it in this pic, but underneath this massive slab has almost certainly been dug out, and I reckon the spoil is too far from the slab for it to have been the work of an animal.Are there any other slabs/stones of similar size visible in the surrounding area?
It's about 10 m from the alignment, and is part of a cluster of similar slabs.
This photo shows more of the context.
The area is strewn with boulders predominantly, these are granite erratics. Outside the cluster of large slabs the area is littered with smaller slabs (possibly chalcopyrite).
It is possible that some of these slabs may have been broken out from the bed rock as trials for metal ore - at some unknown period, but almost certainly pre C.18th
This photo shows the remains of an early wall, about 10m from the alignment. The wall is not shown on the first ed. map.
First ed. view with the crosshairs, more or less on the alignment.
When the site was first visited by an eminent archaeologist, he said "This place reeks of prehistory."
He would not commit to a verdict on the alignment though, and hasn't mentioned it since.
Two other senior archies give odds of about 60/40 in favour of it not being natural.
Another point to consider is that this copse is one of a number in intensively cultivated land.
All of the other copses contain anomalies of some kind or other, such as forgotten mine workings etc. (one copse encloses a national monument).
It's possible the area hasn't been cultivated because of the alignment.
The copse today, broadly fits into the area defined by the two trackways in the image above.0 -

Not much to add in terms of identifying what the site may be... But found this nice Wedge tomb Reconstruction (from http://www.philarm.com/):

Nothing at all wrong with that sketch map Slowburner. Shows the layout of the site perfectly. It's almost impossible to take good photo's in a heavily forested area. If you have brought up a few archies and they think the site looks genuine then maybe you should consider filling out a monument report form..........
http://www.archaeology.ie/media/archeologyie/PDFS/ASI%20Monument%20Report%20Form%20%20(June%202012).pdf
Someone in the ASI will get around to having a look at it and it might be added to the RMP.0 -

I have one of those forms, but I'd prefer to get confirmation before submitting it, and getting confirmation is bit of a challenge.
I'm told the absolute authority on these things retired just after he was given the location.0 -

If you had the time (and inclination) you could make a photogrammetric model of the site using Microsoft's online service http://photosynth.net/ . You basically take 100+ overlapping photos of it, by slowing navigating a 360 degree circuit of the site, snapping away.. Here's an overhead view of a pointcloud of harristown passage grave in Waterford, generated from ground based photography using this service..

Here's my effort at a photogrammetric image.
It's a bit of a disaster I think, because
1. I didn't take enough pictures and,
2. It was impossible to keep at a regular distance from the target, because of the trees.
In spite of my shortcomings, it made a passable effort at a plan view.
Remarkable software, and free to Joe Soaps like me to boot.
