This was taken at Stair hole which is next to lulworth cove. Stair Hole is a small cove situated immediately to the west of Lulworth Cove.

Lulworth cove online:
There is an outer barrier of steeply dipping Porland Stone and basal Purbeck limestones (the Caps).The sea comes through caves in the eastern and central part and an open gap at the western end. The Great Dirt Bed is an ancient soil, a palaeosol, resting on the basal lagoonal limestones. The Broken Beds are an evaporite breccia, and the Cypris Freestones are limestones of pellets and ostracods (the shells of water-fleas) that lived in a very large and rather hypersaline lagoon, almost at the end of the Jurassic Period. To the right of the cave, the soil, the Great Dirt Bed has been eroded away to show the Teepee Structures which are megapolygons developed in the early cemented limestone on which the soil formed. A better place to see all these features is at the Fossil Forest , on the other side of the cove (a broad ledge on the cliffs).

There is an open gap at the western end. This is a collapsed cave and eventually the other caves will collapse in the same way. The open gap here has caused increased erosion of the shales and limestones of the Purbeck Formation, landward of the beach. In storms the seas directly attack this. At the back, behind the Purbeck strata are the pinkish and yellowish mottled clays and sands of the Wealden Group. The sea has not yet been able to erode these so the small cove does not have the same structure as Lulworth Cove with chalk at the back. The Purbeck barrier has been lowered, though opposite the open gap. This cutting down of the vertical Upper Purbeck strata has enabled to Wealden to slump down over it, coating it with red marl.

It has been said that Stair Hole is a " Lulworth Cove in the making " but it is being formed in a different manner from caves being eroded through the Portland Stone, rather than the sea opening up a stream valley.

Thanks for looking

As I've written in the critique, I only rotated the picture slightly to the right in order to get the coastal line in the background straight. I hope you like it. regards, Heike
