Walls Boundary Fault
Began the day heading for Esha Ness, stopping first at Stenness which had been a centre for fishing and there remains an oldfish store.
Continued to Esha Ness lighthouse to see spectacular sea cliffs and geos.
Drove then to Tangwick Haa, stopping to photograph the stacks called The Drongs and arch called Dore Holmbefore visiting the small museum of Northmavine where there is a mystery object, (we thought possibly a waterbath) which they would be delighted for someone to identify. Afternoon tea at the St Magnus Hotel in Hillswick was delicious and great value.
On then to the main destination of the day, the Walls Boundary Fault at Ollaberry.(See also here).
To summarise:- "This forms the boundary with the Walls Peninsular where rocks on opposite sides of the fault have moved relative to each other by more than 100kms, mainly during the Devonian and Middle Jurrassic Periods. Showing as a shallow depression with a boggy floor, the fault has crushed and crumpled schist on the West side against the tougher granite on the East Susequent erosion of the schist formed the sandy bay exposing a steep cliff of granite. This is the best exposure of shear fault in Britain."
The 'boggy floor' was a running stream and treacherous to climb down but with Mr Flum's help I managed and witnessed the scene as described on the information board above. As we returned the rain was lashing down and wind would blow us off the cliff but I wouldn't have missed it for the world.
