Sea cave at the ESE end of a 62 m geo. It may have an ESE supratidal entrance from the beach of Lunna Geo.

Reported location of cave. Photograph from clifftop shows what appears to be a long gully running into the cliff. There may be a cave at the back of the gully but it cannot be confirmed from the image. [Report 1145]

Alternative Names: NS17

Notes: Pastmap Aerial (see below) appears to show that there may be an ESE beach entrance at HZ 20001 70782. The length is what the tunnel length would be if that turns out to be true. There may also be a second, parallel cave tunnel immeditaely to the SSW of this cave, of about the same length.
