Dunnimaol Subterraneous Passage S entrances

Dunnimaol, S of Dunnottar Castle, Stonehaven, Aberdeenshire, (Kincardineshire).

Previously thought to be a separate rift cave parallel to the Subterraneous Passage, on 14 July 22 it was confirmed that the two entrances described below connect to the N entrance. See that entry.

Photo 2 shows the SE side entrance, which is supratidal and obvious. It is at NO 88111 83447.

Photo 1 shows the S entrance which is a very narrow rift - at the NGR above - through which light from the side entrance can be seen.

Notes: Access: By sea. Landing beside the round side entrance may be possible on a high springs tide, in very very low swell.

Not accurately indicated on any OS. The 1st Ed 25" does show a tunnel line - but it is about 16 m too far to the left (W) at the S end and 10 m too far left at the N end. This is entirely understandable based on what you can see from outwith the actual tunnel. See the aerial below.

Photo 1 shows the supratidal side entrance which opens onto the wavecut platform, with a fairly high tide. It was judged that a 4.5 m tide and zero swell would be needed for a landing on 14 July 22. The S entrance is at the extreme left, appearing to be just above sea level on this photo, actually not. Above it, the rift which is apparently in the right place for the S entrance to Dunnimaol Subterranean passage, but it turns out that there is no tunnel there.
Photo 2 shows the intertidal S rift entrance - at the NGR given above. Light from the side entrance of photo 1 can be seen, as indicated.
