Question: Which feature named for he Scottish Gaelic word for lake is south of Beinn Alligin?
Context: Struan (Scottish Gaelic: "An Sruthan" ) is a small village situated on the west coast of the island of Skye, on the shores of Loch Beag, itself an inlet of Loch Harport.  "Struan" is the anglicized form (and approximate pronunciation) of the Scottish Gaelic word "sruthan", meaning "small stream", or the flow at the point where a spring appears. Sròn is the Scottish Gaelic word for nose and is the name of some hills in the Scottish Highlands.  Before the abolition of the acute accent in Scottish Gaelic, it was sometimes spelt as "srón" Beinn a' Chrulaiste (Scottish Gaelic: "Beinn a' Chrùlaiste", meaning "rocky hill"), is a mountain to the north of Glen Coe, in the Highlands of Scotland.  The Mountain is rectangular, and can be seen from the A82 road and the Old Military Road (West Highland Way).  Also, when passing the A82, it is possible to see the summit of Stob Dearg (Buachaille Etive Mòr).  Beinn a' Chrulaiste stands at 857 m (2811 ft), making it a Corbett. The River Orchy (Scottish Gaelic: "Urchaidh / Abhainn Urchaidh" ) is a river that passes through the village of Dalmally, Argyll in the West Highlands of Scotland.  It rises in the Black Mount Forest, and flows southerly, passing through Loch Tulla and Glen Orchy before reaching Loch Awe.  The hills of Beinn Mhic-Mhonaidh, Beinn Udlaidh and Beinn Bhreac-liath are to the north and south; there are falls and islands within the river.  Reachable by the A82 road, tourists partake in kayaking, whitewater rafting, and fishing.  Recent gold mining exploration has occurred in one of the river's glens just outside the Loch Lomond and The Trossachs National Park. Beinn Alligin (Gaelic: "Beinn Àilleagan") one of the classic mountains of the Torridon region of Scotland, lying to the north of Loch Torridon, in the Highlands.  The name Beinn Alligin is from the Scottish Gaelic, meaning "Jewelled Hill".  The mountain has two peaks of Munro status: Tom na Gruagaich (922 m) to the south, and Sgùrr Mhòr at 3,235 feet (986 m) to the north. Loch ( ) is the Irish, Scottish Gaelic and Scots word for a lake or for a sea inlet.  It is cognate with the Manx lough, Cornish logh, and the Welsh word for lake, llyn. Craig is an English-language masculine given name of an ultimately Celtic derivation.  The name has two origins.  In some cases it can originate from a nickname, derived from the Scottish Gaelic word "creag", meaning "rock," similar to Peter.  In other cases, the given name originates from the Scottish surname "Craig", which is also derived from the same Scottish Gaelic word.  Cognate forms of "creag" include the Irish "creig", Manx "creg", and Welsh "craig".  The English word "crag" also shares an origin with these Celtic words.  The given name "Craig" is popular in Scotland, and is used throughout the English speaking world, though in North America it is often pronounced with a short vowel sound, as in "egg", while the British pronunciation sounds like the diphthong in "brain". Ben Vane (Scottish Gaelic: Beinn Mheadhain) is a Scottish mountain situated in the southern Highlands.  The underlying geology almost entirely comprises the Beinn Bheula Schist Formation - Psammite and Pelite with a Siluro-Devonian Dyke prominent round the northern and eastern face.  It is one of the Arrochar Alps and stands slightly separate from the other mountains of the group being connected on its western side to the neighbouring Beinn Ìme by a low col at 492 metres.  Ben Vane itself just qualifies as a Munro reaching a height of 915 metres (3002 feet) and is characterised by steep and rugged slopes which fall away to the Inveruglas Water to the east and the Allt Coiregroigan to the south; to the north the descent is more undulating going over the subsidiary top of Beinn Dubh before falling to the valley at the north end of Loch Sloy.  Dense forestry cloak the mountain on its lower southern slope in Allt Coiregroigan.  Also on these southern slopes by the Allt Coiregroigan is a disused quarry which provided crushed stone used for the construction of the Loch Sloy dam in the late 1940s.  The dam wall lies two km to the north of the quarry and a conveyor belt was constructed to carry the crushed stone over the lower slopes of Ben Vane to the batching plant beside the dam. A rolag (Scottish Gaelic: roileag) is a roll of fibre generally used to spin woollen yarn.  A rolag is created by first carding the fibre, using handcards, and then by gently rolling the fibre off the cards.  If properly prepared, a rolag will be uniform in width, distributing the fibres evenly.  The word derives from the Scottish Gaelic word for a small roll.   Alasdair Crotach MacLeod (Scottish Gaelic: Alasdair Crotach MacLeòid) (1450 – 1547) is considered to be the eighth chief of Scottish Clan MacLeod.  He was the son of the seventh chief William Dubh and succeeded his father in 1480, following William Dubh's death at the Battle of Bloody Bay.  He was the first MacLeod chief not to be buried on the island of Iona.  The Scottish Gaelic word "crotach" means "humpbacked" and the nickname refers to wounds he received during battle which crippled him the rest of his life.  Alasdair Crotach's tomb is one of the most magnificently carved tombs of its era in Scotland.  He was succeeded by his son, William.
