| Description: | The River Clyde at Stonebyres Falls, 2.4 km. west of Lanark, Lanarkshire. Lower Devonian (formerly Lower Old Red Sandstone) sedimentary rocks of the Lanark Group dipping upstream, producing the stepped waterfalls of Stonebyres. The gorge below is being formed by the retreat of the waterfalls. Gently dipping successions of alternating hard and soft beds typically give rise to a series of stepped waterfalls of the 'Niagara' pattern, such as here. 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. |
