Where Am I? No. 235 - Coast Scene

[ScouseBoy]

There could  once have been a piece of military equipment mounted on or attached to the small piece of rock.  Such as a searchlight or an attenna (aerial)        (Taking some ideas from the details offered by the Tenby theory)
The narrow "path"  is consistent with  camouflage of the cables, as practiced  by the germans  as well as by the British in  concealing Radar installations.

As at Dunnett Head on the mainland of Scotland

Ground a the top of the cliff is very flat and seems to be fields right to the edge, does not look like a costal pathway.

A few random thoughts -  is there a road running along the near edge of the cliff on the other side(looks like a white line) ?
Has anybody an idea what the two posts are at the front edge of the photo, are they on the shore or perhaps a boat?
Are there a couple of people on the other side, one with a white hat, as seen in the photo posted by Nick_Ips in #52?

I'm wondering if the 'post' on the right at the front edge of the photo is a lookout binocular. So I would guess it was on the shore rather than in a boat. It would seem to be aiming towards the rock formation. I've been wondering if it's the geological formation that is the focus of interest in this photo.

Not sure about the 'post on the left at the front edge of the photo but have been wondering if it lines up with the 'post' on the far shore that you referred to as Loch Ness monster in reply #10 (which made me chuckle at the time  )

I was just about to say the same Geoff-E.Doesn't  look like the Jurassic Coast in Dorset,but might be worth a look.I wonder how old the photo is ,as there doesn't seem to be any regeneration.

I'd say Edwardian.

Looking at the geology the size of the landslip is considerable and presumably indicates a rock formation that is prone to landslips, with other smaller slips further along the coast?   

The construction of the bridge in the foreground should be on a rock formation that is more stable or the bridge wouldn't have built - however it does look are though the bridge links to a rock headland  separating  by a fault line from the main coast.  So how strange to build the bridge and the associated well constructed walls on this unstable coast line unless the photographer is looking out from part of a much larger site which was of importance

   Yes, I think the two things on the bottom edge of the photo are part of a boat.

I will risk the opprobrium of my fellow Rootschatters by making a comparison,hopefully to similar scale,of the posted photograph and a presumably much more recent one(desaturated).Given the fact that there may be 100 years or so between them and they are from slightly different angles,I still find the comparison interesting(including the white footpath(?) above the geological feature)
Could there have been a bridge that allowed access perhaps to the tip of Porth Island 100 years ago?

The geology is interesting, but I'm not sure it helps much with the why (or why not) the bridge is there.

The coast in the background is made up of different types of rock, I've indicated the boundaries between them with purple lines. The area with the landslip is possibly a much softer rock (perhaps limestone?) in an area which is generally harder. If you look closely at the point I've marked with an arrow it appears the soft rock is actually being eroded from behind the harder material to the left. It is a similar kind of process which would cause the cave-like structures. The process here is one of wave action undermining the toe of the cliff causing the material above to fall and would be happening constantly.

In the foreground, the rocks are generally harder, but the 'island' does show some movement. Although it is difficult to be sure without a colour photo I've indicated the different layers (bedding planes) with red green and blue lines. This illustrates that there has been a slip along a fault shown roughly by the orange line. But that is a movement associated with a very long time period, or a very dramatic event (earthquake), so unlikely to pose much of a concern during the lifespan of the bridge.

The bridge itself is of a very simple construction and relatively low cost - the kind of thing a council would use on a public footpath to cross a stream or small river. It would also accommodate quite a lot of vertical movement at one end before becoming unsafe, so the builders would not have been particularly concerned about movement of the rock causing their hard work to be wasted.

Like ScouseBoy I did wonder about it being used for some kind of military installation. But the solidness of the walls on the right-hand side suggest to me that this wasn't something designed for use by the military or civil organisation - for them I'd expect to just see a sign saying 'keep away from the edge', or a barrier of wire or rope. Employee safety then would have been on the basis of common sense rather than having such a heavy physical barrier.

For me the construction of the walls very much suggests this is something the public have regular access to, either as tourists, or that the area to the right is inhabited.
