Upon a well worn pathway exists a large flat boulder, with many well defined cup marks.
If you think they are all ‘natural’, I would argue that such linear and equilateral triangular designs seem more man made.
50pence coin gives the scale, and also the possibility of more worn, possible older carvings – highlighted in yellow on the attached images
