Amongst the large boulders and standing between two small up-right stones there is a large, long stone with a flat side to it. On this is carved a thin Latin cross surrounded by an inscription in what has been described as old school Latin - this must be different in some way to Roman Latin, though there does not appear to be any significant difference. The inscription is IESV DEVS DOMINVS MONTIVM which translated means 'Jesus, God, Lord of the Mountains'. The stone rests on recumbant stones and sits between two thin standing stones, one smaller in height than the other - in other words these stone have been placed to look like a church altar or similar.
The stone is probably pre-16th century due to the type of Latin used; it was probably a way-marker or boundary stone, but with a religious connection. Some historians think it was a boundary stone marking the land belonging to Whalley Abbey. So possibly we have a pilgrimage route from the abbey to Yorkshire. Certainly this secluded ravine is a heavenly spot, a place of peaceful serenity and tranquility. I have no doubt that the stone was visited by pilgrims as far back as the 14th-15th centuries who would pause here and offer prayers. There is, apparently, a baptismal pool in the stream that flows down the clough, though I don't know whether it still exists today.
Whirlow Hill a few miles to the east was where some beaker artifacts were excavated and a bit further north still we have the famous Bridestones. So enjoy your walk but mind how you go when clambering over the rocky outcrops.
