The word "may" is doing real work here. Nothing is visible at ground level, and the site leaves no trace on the landscape that a passing walker would notice.

What makes this particular absence interesting is the cartographic record. The Ordnance Survey's six-inch map of 1837 makes no mention of anything here. But by the 1913 edition, the word "Cave" appears at or near this location, suggesting that by the early twentieth century someone, whether a surveyor, a local informant, or both, understood there to be something underground. Whether that annotation reflected a known local tradition, a partial collapse that had briefly made the feature visible, or simply a piece of inherited knowledge passed along to the mapmakers, is not recorded. The 1913 label is tentative evidence at best, and the site as it stands today offers nothing more concrete.
