A glen in Killninver, Argyll, is called 'Gleann-uraisg,' 'Gleann na h-uraisg,' glen of 'uraisg,' glen of the 'uraisg.' Many stories are told of the 'uraisg' possessing this glen, the appearance, the action, and the speech of this supernatural creature being graphically described. The 'uraisg' is not unfriendly to the friendly beyond showing them scenes, and telling them of events above the world, upon the world, and below the world, that fill them with terror. Strong men avoid the glen of the 'uraisg' at night.
In the Coolin Hills, Skye, there is a place called 'Coire nan uraisg,' corrie of the 'uraisgs,' and adjoining it another place called 'Bealach Coire nan uraisg,' the pass of the corrie of the 'uraisgs.'
