This gryke gives shelter to the kind of plants that you’d see in a hedgerow or in woodland. A velvety coat of moss on the limestone indicates how far the humid, sheltered zone of the gryke extends. In this particular crevice I noted wild garlic, dogs mercury, meadowsweet and creeping thistle.
A gryke is a crack between the clints (slabs) that make up a limestone pavement.
It might be sheltered for the plants down there but there was a cool breeze blowing down the valley this morning and the slab of limestone that I was sitting on proved surprisingly uncomfortable, even though I was sitting on a thin foam mat, so this is as far as I got with my sketch.
