| Caption: | Valley of the Braid Burn between Blackford and Braid Hills, south side of Edinburgh. Midlothian. |
| Description: | In the wood beyond, the stream has cut a post-glacial gorge through a rock spur of trachyte lavas.The valley holding a misfit stream, was carved out by ice deflected round the south side of Blackford Hill and was further deepened as the ice melted and large amounts of water flowed through from the Water of Leith at Colinton. Normally a stream cuts a valley into which it fits exactly, a misfit stream is where a stream flows in a valley that is far too large for it. The large valley formed when there was a lot more water available for erosion, in this case, when the glaciers melted. Another cause is reduced annual rainfall. In the foreground the stream has excavated an old preglacial valley by removing the boulder clay (left), from the old rock-slope of the Lower Devonian trachyte and andesite lavas (right). |
