Cave

Once set up we immediately set off cave-hunting and Dr.B. quickly found the obscure entrance to Gunna Mor situated in the basalt pillars a few metres above sea level on the north side of Port an Fhasgaidh inlet. This peculiar cave, later surveyed to a solid end at a mere 5.07 metres, is somewhat of an anomaly on this basalt island. Inclined upwards at 35 degrees it resembles a 1 metre diameter phreatic tube and theories on its formation abound. A small "rockmill" pool at the entrance apparently once held a large round stone weighing 5 lbs which was violently agitated in storms to give the cave its name. A legend states that the stone was pinched before 1800 by Irish tourists.

Alternative Names: Gunna Mor, Cannon (The)

Notes: Literally the big gun on the W of the island, NW of Port an Fhasgaidh.
