A vertical rift cave/tunnel running about 235/055 (WSW/ENE) through a rocky spit. This entrance is quite near to Captain Ivory's Cave. It is straight and, in places, narrow so that you have to turn side on. At the northeast end you have to crouch a bit. This entrance width is 3.0 m.

Alternative Names: None recorded.

Notes: Access: from Strathy cemetry over the dunes to the east side of the beach. This is the 3rd cave you come to.

VR of this entrance and width measured on 22 June 24 by N Feilden. The compass bearing was 228. An attempt was made to measure the length with a LDM which was written down as 24.3 m (sum of 3 rdgs). The aerial view shows this must be much too short and the above length is derived from this NGR and the best estimate of the south entrance NGR.
