This prehistoric carved rock, found within the Slade area of Blubberhouses Moor, North Yorkshire, was discovered in July 2011 by Paul Bennett and listed on his Northern Antiquarian website: https://megalithix.wordpress.com/2011/07/10/slade-carving02/ At first glance, the markings look relatively simple, but the positions of the rings draping over the edge of the rock is quite unusual and probably suggests careful placement. Using virtual light it’s possible to see how natural contours of the rock give the illusion of a 2nd ring on the lower motif. A difference in carving depth between the two motifs is apparent when viewing a higher resolution model with the lower ring cutting into the shallower higher ring. This may indicate possible superimposition and two different phases of carving. A linear groove tracing the upper edge of the rock may also emanate from the shallow upper ring. Model created from 26 images captured in September 2015.
