CLEVELAND - Esk Valley Storregga slides Stunami theory

I now believe the flood event Ive previously said created the Stainton gravel beds and Alluvial sands and clay layers above, could have possibly been caused by one or both of the Holocene Storregga slides. Storegga Slide - Wikipedia,  7 - 8000 ybp, I based my previous dating for the superficial deposits of the area of my work, in the south west area of Cleveland, on Geological records that were adamant that the superficial deposits of this area, had to have been created by the retreat of the last glaciation 12 to 17000 ybp, as stated above i now think there is a good possibility that one or indeed both of the Holocene Storregga slides and the subseqent tidal waves could have created the deposits we now walk upon in south west Cleveland.   HISTORY OF A BECK: The Stainton gravel beds

1- Map showing the location of the Storregga slides.

 2- Deposits left by the Tsunami on the east coast of Scotland very similar to deposits i have excavated in the beck valleys of south west Cleveland.

 My idea is this, i believe the tsunamis caused by the slides could have created enough tidal energy to create a wall of water, sediments and gravels, that was capable of travelling inland as far as Yarm, firstly using the Esk Valley then Leven Valley, and the now deep beck valleys etc.

 3 - Stainton gravel bed deposits the red outline marks the gravel bed, the yellow outline marks the grey organic layer above.

 3 - Close up of the Stainton gravel beds taken by my good friend Andy Cooper a local Geologist, showing organic remains, i have since discovered Human and animal bones in the gravel beds.

 4 - Please note how many separate compact layers of sand and clays the gravel beds are covered by.

 5 - The gravel beds in this image are exposed at Maltby beck shown just above the spade handle, the gravel beds here only a short distance from the Stainton deposits, look to have been cut through by the beck a lot earlier than at Stainton, possibly thousands of years, hence the lack of fossils and sub fossils at Maltby beck.

The lower deposits are as yet a total mystery.

 6 - This image shows the same deposits a quarter of a mile east at Stainton beck, although the brighter clay deposits at this location have yet to be exposed by the beck flow.

 7 - This image shows a close up image of the gravel bed below, then the ever preasent blue grey organic deposit then sandy clay.




This theory would go a long way towards explaining my Geological descoveries in the south west area of Cleveland, but it would be an amazing surge of water needed to travel this far inland to create, the deposits i now excavate & descover both human and animal sub fossils. HISTORY OF A BECK: The Stainton gravel beds  -  HISTORY OF A BECK: Maltby deposits

The link below shows a simple map of the area and the route i believe the huge surge could have followed, the area in blue shows the areas i know to have the same ordered superficial geological layers

Please feel free to correct me on any part of my blog, i would also welcome any help that can be offered in correctly identifying some of my fossil finds All the best to all Heath.
