“Castlerigg in Cumbria was until quite recently without any recorded rock art. The author (Stan Beckensall) recorded one cup marked stone built into a modern wall nearby, and then two students from Newcastle University, Nick best and Neil Stevenson, photographed a spiral on one stone in late afternoon sunlight in 1995. later they found incised lozenge motifs on two other stones, and I found a cup and ring at the top of another.”
