Not a single coherent inscription, not a monument designed to be read by posterity, but a loose scatter of straight lines, x-shapes, chi figures (a chi being a cross-like or windmill form, the kind of mark that sits ambiguously between a letter, a symbol, and idle geometry), and several sets of initials. One of the chi figures has been enclosed within a U-shape, a small deliberate act that sets it apart from the rest without fully explaining itself. The overall impression is of a surface used informally across time, perhaps by more than one hand.

The markings were recorded by Finlay in 1973, who noted they occupy a patch roughly 1.3 metres long and a metre wide on the exposed rock. That combination of elements, initials alongside older-looking geometric forms, suggests the surface may have attracted attention and intervention across a considerable span of time. Initials cut into rock are often a relatively modern habit, the impulse of a shepherd or a traveller marking passage through a place. The chi figures and other geometric incisions are harder to date and harder to read. They could belong to the same period or to something much older; without excavation or closer analysis, the sequence remains open.
