Geodha Mairi East Cave

SE corner of North Rona, Wester Ross.

'The cave consists of a narrow (2 - 3m) wide canyon. It opened directly into the base of the cliff and ran approximately south for over 65 m into the island. It was not followed beyond this point due to wave surge and time constraints. The cave passage was [very] approximately linear in plan view, tended to be broader near the floor, and tended to become narrower overhead.

The floor was at a depth of ~17.5 m BCD at the entrance, rising to ~ 11 m BCD 65 m into the cave. It was composed of rounded boulders and bedrock outcrops with patches of mobile sand. The cave walls were generally steep being mainly vertical or slightly overhanging although small ledges were also present in some areas.' [Report 1044]

The entrance photo shows it to be formed on a rift leaning about 24 degrees right (W).

The plan shows the cave to be somewhat banana shaped - facing 016 (a bit east of N by E) and curving round to -018 = a bit west of N by W.

Alternative Names: Jo's Cave, CV03, CI24

Notes: The length is clearly quite a bit longer than 65 m. The height ACD was estimated from the further away entrance photo to be 13.3 + 1.0 = 14.3 ACD.
