| Description: | River Clyde, looking downstream from Corra Linn, 2.4 km. south of Lanark, Lanarkshire. Gorge cut in sandstones of the Lanark Group (formerly Lower Old Red Sandstone) immediately below Corra Linn, formed by retreat of the waterfall upstream. The extent of the sudden change in elevation of the river bed across the waterfall can be gauged from the height of the cliffs forming the wall of the gorge. Note the jumbled piles of sandstone blocks in the bed of the river, debris of the harder beds which formed the top of each step in the waterfall. Gently dipping successions of alternating hard and soft beds typically give rise to a series of stepped waterfalls of the 'Niagara' pattern, such as at Corra Linn. The harder beds form the top of each cascade while the intervening softer beds are continually undercut by the river. Eventually, support for whole sections of the harder beds is removed and they fall into the pool below. In this way, the whole waterfall thus gradually retreats upstream. |
