If you follow the track that leads west from the Haystack rock and then swing round to the south you pass the partly reconstructed Backstone Beck Enclosure. Between the arc of drystone walling and the path, and northwest of the hut are 3 carved rocks nestling in the undergrowth and almost in a northwest line. Due to the covering of heather on this part of the moor the stones can be difficult to find despite the fact that one stands almost next to the track. The first stone measures 180x130cm with around 45 cups, a couple of unfinished rings or arcs and several grooves - it lies just to the east of the path. The second stone is a little further southeast, it has about a dozen cups, 2 of which are quite deep, and measures 170x130cm. The third stone which lies nearest to the enclosure itself is a beautifully carved rock known as the Second Idol Stone
