Also known as Slack’s Gill and until recently buried inside the commercial forestry of Black Bank. It’s my ‘secret’ way up onto Great Ayton Moor. Mine and the mountain bikers who created a downhill course through the wood. But the clear felling has put paid to their activities. I am sure the sandstone crags have been quarried but there is no evidence of the route the stones would have been hauled down the slope. The large boulder in the gill does have an anchor bolt on the top but I guess that could be modern, placed as a protection for rock climbers. I’ve rendered the photo into black and white as the carnage left by the clear felling is hidden.
