Clach nan Taillear Literally "stone of the tailors" (Watson (1975)) is a large ribbed stone by the side of the Lairig Ghru track close to where the Allt Coire an t-Saighdeir joins the river. Gordon describes how this stone got its name, writing: River Dee Although all the rain that falls on the slopes at either side of the southern half of the Lairig Ghru eventually drains into the River Dee and the "official" source of the River Dee, the Wells of Dee, is high on Braeriach, the River Dee (as a named watercourse on maps) starts at the confluence of Allt a' Gharbh choirie and Allt na Lairig Ghru. At this point, near the head of Glen Dee, the main valley turns roughly west towards An Garbh Choire, and the Lairig Ghru track continues northward into the hanging valley as shown in the photograph. The Duke's Path Only shown on the 1:25,000 scale maps, The Duke's Path is a made-path on the western side of the Lairig Ghru, following the course of the burn draining Coire Ruadh and leading to the bealach between Braeriach and Sron na Lairige. During the nineteenth century, what was then the Mar Estate (see Mar Lodge Estate), was a private hunting estate owned by the Duke of Fife (created Duke in 1889, and dying in 1912). In Gordon (1925) the author describes using this path on an ascent of Braeriach, continuing: Pools of Dee The Lairig Ghru track winds around a series of pools on the Mar side of the summit. These are thought by many (incorrectly) to be the source of the River Dee. Watson (1975) explains that the Pools of Dee are an invention rather than a pure Anglicisation of the old name Lochan Dubh na Lairige (black tarn of the Lairig). At least one of these pools is reputed to contain trout in spite of these pools having no obvious outflow, nor inflow. Slightly to the south of the largest pool, the burn named Allt na Lairig Ghru flows from the floor of the valley flowing south to join with the burn named Allt a' Gharbh choirie to create the River Dee proper.
