Title: Bullet holes on rock
Post by: tomtom on September 03, 2014, 05:42:54 pm
Hello all,
I was chatting to a researcher at a conference yesterday who is looking at how bullet holes interact with rock - what size holes they make, patterning etc.... theres a science reason somewhere but I've forgotten it.. They've been looking at bullet holes/marks on buildings (spain, dublin) as a starting point (you know when they happened etc..)...

So over a beer, I mentioned that there are several climbing places where there are bullet holes/marks and they are often an integral part of a problem (I thought of BBG West at first) and they were really interested in where these might be... I've a feeling there are loads - so does the collective mind of UKB any suggestions?

I guess one of the Wiltons as there is a firing range up there (but not been there for 10 years or so - so forgotten) - isnt one of the southern sandstone crags in a former shooting range too?
Cheers,
T

I always thought the "pocks" on the pock block were from bullets.

Pex Hill is riddled with them. They make Pisa Wall the Mecca for super open drag pockets.  I think one of them still has the bullet embedded in it.

I was always led to believe that too. That and a few other boulders at Burbage south apparently.

Burbage south boulders.
Some shot wounds at Thorn.

Burbage South boulders are the most obvious.

Could be wrong but from memory I think there are some on Dick Williams at Secret Garden? May even be used as holds.

There's bullet wounds all over burbage west, south, higgar etc. Think the valley was used for training during one or both of the wars. Read somewhere it was the home guard.

There's no bullet wounds on dick Williams that I can remember.

There is one that looks like it could be on hairpin boulder at froggatt.

Pretty sure there are a few visible at Bowden Doors too, especially in the Y Front area.

I'll have to check with my contacts, but Canche aux Merciers used to be heavily used by the army, was in a terrible stater for a long time. Hard to believe they didn't get up it on Pastis and start shooting boulders. Never thought about it before, interesting. I'm sure some of those finger pockets could be bullet holes.

another shout for pisa wall at pex hill, loads of them

Post by: tomtom on September 03, 2014, 07:03:35 pm
Some good shouts there - thanks - keep em coming... hadnt thought of pex... are they not all partially rubbed away now/smeared out due to the years of shuffling?

Its probably quite important that they can constrain the dates of when the occurred... for example Pex might be a nightmare if it was used on and off for 50 years (just an example - I don't know) - whereas BBGWest might be great as this was just during WW2 - so we know they're 70 years old etc... this also gives you an idea of what weapon was used (relating to the size/velocity of the projectile etc..)

Also good to have them on a range of materials (sandstone and grit so far)..

Can't believe you've not done it Tom. Pretty tough 5c. The boulder is riddled with billet holes, as are most of the boulders around there.

Barring nearly every boulder in burbage valley (daves right - it was owned by the MOD for training in the WW2 and Sheffield City Council did quite well to buy it off them in the 50's by all accounts)..... most obvious to me would be the wall to the right of Cordite crack in Lawrence field. There's a clue in the name of the routes round there.  The gun that made them was an Anti Aircraft gun mounted on the concrete pillar with a stainless steel pin in the top that you pass as you walk away from Gingerbread slab towards the said routes.  I'm guessing the lads in charge of it thought they'd better just test to see if was working like.
Gives you a date, quite possibly an accurate guess at the gun and they are fairly untouched I guess.

interesting post.

 :lol: trouble is a lot of them are a lot bigger and worn than they were twenty years ago, this one in particular.

Canache aux merciers was not a live fire area, there used to be loads of brass but they would have been using BFAs, and I can't remember anything like a bullet hole either.

I'm fairly sure there's an old video with James Litz and co. chipping a problem by shooting it.  Presumably (and hopefully) a rare example of it actually being done deliberately by climbers.  Possibly on an old Momentum thing or something like that.

I have been there - in fact I believe it was with Mr Bieretoilepoisson... I didn't know it was called the pock boulder.

I think I did the 5c.... Thanks for the link Galpinos and other info people. V. Useful. Let me know of any others and I'll pass on if it comes to something or not... (Science wise)

The big starting jug on the La Puce dyno has a blank 5.56mm round lodged behind it.

According to this page : http://teessidewandering.wordpress.com/2010/11/27/ml-training-burbage/ (http://teessidewandering.wordpress.com/2010/11/27/ml-training-burbage/)

Quote
The Burbage Valley was used for military training during World War 2 by a number of units between at least 1941 and 1944. There are numerous earthfast boulders scarred with bullet holes, mortar shell scars and at least four filled-in foxholes. Some of the boulders give the appearance of concrete pill boxes. The majority of boulders are usually hit only on one side. The troops were British and Canadian.

Which narrows down the dates, and might help with the weapons used?

I sometimes climb with a guy who refers to all pockets on  grit as bullet holes. I assume this comes from starting out at the Burbage South boulders but I've never figured out whether he thinks all pockets were created in such a way or not.
