What is recorded here

Coomasaharn holds ten small cupmarks carved into a flat sandstone slab beside the Behy River valley. Six cluster at the high NE end and four rest at the SW end, spaced across a surface wide enough for both hands to span. The bog has cut back around the stone, leaving the marks exposed on a sloping bank where water still runs nearby. Whoever made them worked a rough rock into a deliberate line of holes, perhaps counting, marking ownership or pointing someone toward the river below.

In cutaway bog, on a NE-facing slope (157m OD), c. 13m to SE of field boundary and stream/land drain. Good views of Behy River valley to N. A slightly rough and fractured sandstone rock (dims. 2.60m NE-SW; 1.60m NW-SE; 0.40m (max. H at NE) with an irregular-shaped decorated surface (dims. 1.75m NE-SW; 0.55m NW-SE) which is flat. The rock art is clearly visible and consists of six cupmarks (diam. 7cm; D 15mm) upon the highest part of the stone at NE-end. Four cupmarks (max. diam. 6cm; max. D 9mm) at SW-end.

Likely dating to the Neolithic or Bronze Age, the rock art at Coomasaharn may have had ritual or territorial significance, possibly linked to landscape features such as the nearby Behy River. No specific folklore is recorded for the site.
