Man-made underground passage in Garradevlin — Report the wrong picture

What is recorded here

No stones remain, only a long shallow ditch and a shorter spur cutting across the western rise inside the rath. The shape suggests a buried passage that collapsed or was filled, leaving behind a hollow rather than a hole. Anyone walking that drumlin summit would have felt the ground dip unexpectedly, as if the earth had forgotten how to hold its own shape.

Situated on a summit of a NW-SE drumlin ridge. There is a natural rise inside the inner bank of rath (MO019-028----) at W with a sunken area (L 10.7m; Wth 4.4m; D 0.5m) across it NE-SW that has a spur (L 3.4m; Wth 3.2m; D 0.5m) extending NW off its SW end, which might be a collapsed Man-made underground passage, although no stones are present.
