These two stones are situated on the northwest side of Backstone Beck on the opposite side of the stream to Backstone Enclosure. The first stone (PRAWR 283) stands at SE12744625 in the middle of a track that leads south from the Cow and Calf rocks passing the disheveled Backstone Circle before heading towards the Twelve Apostles stone circle. It is an almost square flat rock measuring 120x110cm and has around 45 cups, a ring and several deep grooves. One of these grooves runs along the line of a natural fault in the stone.
Just to the northwest at SE12724627 is another carved stone (PRAWR 282) that is difficult to find amongst the heather growth. It measures 180x120cm and has over 30 cups, 3 rings, 6 or more penannulars or unfinished/eroded rings and a couple of grooves, although it is possible that these grooves could be natural rock features.
