of the giant) to the south which provides an escape route from the Grey Dog. The only other anchorage for passing yachts is at Poll nan Corran (the sickle shaped pool), on the east coast, which has a pebble beach. Geology Prior to the Pleistocene ice ages Lunga was part of a long peninsula stretching south west parallel to Kintyre. The Firth of Lorn glacier sliced this peninsula into several islands, including Islay, Jura, Scarba, Lunga, Luing and Seil. Later changes in sea level left raised beaches over much of the west coast of Scotland and Lunga has several examples. The bedrock of Lunga comprises a mixture of quartzite, limestone and shale called 'Scarba conglomerate' which predominates to the west and in the tidal islands to the north, with schist and mica-schist to the east. Unlike the other Slate Islands immediately to the north there is no commercially viable slate on Lunga, although the slate workers of Belnahua made use of the fresh water spring known as Tobar a Challuim-Chille (the well of St. Columba's church) north west of Bidean na h-Iolaire during times of drought. It is a trough, made up of flagstones, which reputedly never runs dry. History The legend associated with the Bealach a' Choin Ghlais is part of the same story that surrounds the naming of the nearby Gulf of Corryvreckan (English: the speckled cauldron). This is where the Norse Prince Breacan of Lochlann is said to have drowned when his boat sank there, so giving his name to this great whirlpool. The prince's dog managed to swim to land and went in search of his master. Failing to find him on Jura or Scarba he tried to leap across the strait to Lunga, but missed his footing on Eilean a' Bhealaich which sits in the middle of the channel between the two islands. He slipped into the raging current and drowned as well, giving his own name in turn to the strait where he fell - the 'pass of the grey dog'. Lunga was mentioned by Donald Monro in his 1549 manuscript Description of the Western Isles of Scotland. He stated that "Lunge" was "three myle of lenthe, twa pairt myle of breadthe, with a paroch kirk, guid main land, inhabit and manurit, guid for store and corn.
