East entrance to quite a long tunnel/subterranean passage, which is probably subtidal.

Patricia Neimann's photo seems to show a natural arch running roughly west to east facing seawards.

Notes: Marked on OS maps as Caves (either side of a small promontory) and as natural arch, north of Wife Geo.

Length from NGRs of the ends - based on Canmore Aerial. Altitude is ACD, and is an estimate.
