As built, it comprised a 14.7-mile (23.7 km) long main line between the River Trent just downstream of Trent Bridge in Nottingham and Langley Mill in Derbyshire. The result is that the sediments took on the shape of the now-vanished halite crystals.The Nottingham Canal is a canal in the English counties of Nottinghamshire and Derbyshire. Over time, as the layers compacted, the surrounding muds, silts and sands would have been squashed into these hollows, using them like blacksmith would use a mould for casting molten metal. It was then likely dissolved away by percolating water, leaving behind hundreds of small, cube-shaped hollows. The halite, which has a wonderful cubic mineral shape, formed just underground in this dry environment. Unfortunately, the halite is long gone, but the evidence of its presence remains. These cubes are often referred to as ‘hoppers’ and formed due to the presence of another type of salt called halite, which is the very same salt you have on your dinner table - sodium chloride. Again they are best seen on blocks that have fallen from the outcrop. The gypsum isn’t the only evidence of a salt at the outcrop some strange, small coin-sized ‘cubes’ can be seen on some layers. The gypsum actually grew within the layers some (unknown) time after the other sediments were deposited, likely after the original sediments formed into rock.
These are most easily seen in the bits of rocks that have fallen onto the ground and look exactly like any sand ripple you’ve ever seen at the beach, but made of rock. Whilst the small cliff looks like it is made of lots of horizontal layers, there are several more subtle features to find, including some ancient ‘fossilised’ ripples. The rock itself is comprised of a mixture of mudstones and siltstones (mainly pinky-red and grey-green), very fine-grained sandstones (mostly yellow-red) and gypsum (white). These colours are often arranged in horizontal layers. What the rocks tell usįirstly, you’ll see that the rocks have a variety of colours: pinky-reds, grey-greens, yellow-reds and even bright white. Almost exactly adjacent to the weir, in one of the river banks, you can see a relatively good example of the local sedimentary rocks called the Mercia Mudstone Group. It’s obvious when you’re getting close to your destination due to the white noise of the river gushing over the weir.
Please make sure you assess the conditions before venturing on these paths, good footwear combined with caution will never go out of fashion here. These paths, though functional, are not as well maintained or sturdy as the main cliff path. There are a couple of paths that branch off from the cliff walk which lead to a weir in the river.
