The rock face in the Torrs

by

What a complete change of atmosphere down here at the bottom of the gorge! The noise of the town is completely drowned out by the cascades of water. The sound is echoed off these tall stone cliffs and massively impressive viaduct arches.

Take a look at their stonework and then back at the rock face. Yes, it is indeed the same kind of rock, a tough sandstone. All of it was quarried right here. What would have been a much narrower gorge has been made wider from quarrying, leaving quite a smooth surface – now a proper challenge for local rock climbers.

One of this sandstone’s features is variability; some of it is coarse-grained, suitable for those massive blocks in the pillars, while elsewhere it is fine-grained and ‘flaggy’ – in other words it can be split into thin slices. Stone floors and even roofing slates for houses and mills could be made from this type.

The Confluence with Black Brook

by

Here is another major convergence of streams, adding yet more power to the River Dane as it carves its way down towards the Cheshire Plain. This is where Black Brook joins the river. Look in the water and we can see how Black Brook got its name.

If there has been a lot of rainfall, the water may look like strong tea, without milk. This dark brown colour comes from peat staining the water. Peat is found on the high moors where both the River Dane and Black Brook have their origins

Black Brook is fed on one side by water running down from the back of an escarpment called the Roaches.  Their name comes from the Norman French word ‘roches’, meaning simply ‘rocks’. There are some dramatic cliffs and spectacular wind-sculpted rock formations up there – well worth exploring another day.

Lud’s Church exit

by

Before we leave the magic of Lud’s Church completely behind, we ought to consider how such an extraordinary feature came to be. Of course, there is a folk tale involving the Devil making a giant gash in the earth with his finger nail.  More logically, can you find any signs of erosion, by water for instance?

This in no way looks like one of those small, water eroded cloughs. In fact, there is no sign at all that a stream has ever run in or out of here. For the record, Lud’s Church is around 17 metres deep and 100 metres long. The sides may be jagged, but they are straight drops of gritstone, draped with cushions of soft moss. There is not much of an eroded look about them.

Think back to the wider picture, though. The River Dane managed to find a passage through the hard gritstone wall of the Roaches somehow. There must have been a weakness. In fact the gritstone of this whole area is traversed by numerous ‘faults’ – cracks inside the rock. These run northwest to southeast, just as Lud’s Church does.

Where the bed of gritstone dips to the north, into what is known as the ‘Goyt Syncline’, a large mass of it simply cracked away. The rock slipped downhill a few metres, breaking along one of these fault lines. This sudden movement under the force of gravity opened up the chasm as we see it today.

Inside Lud’s Church

by

Spend a few minutes simply taking in the atmosphere of this incredible place; the mossy walls, the clumps of fern, the absence of direct sunlight. There are hidden niches and side-aisles too, so have a good explore.

It is not hard to imagine that it must have been a centre for pagan worship long before the arrival of Christianity. There are even signs that modern day pagans revere the chasm, from the little offerings you may spot here and there. It is a deeply hidden place.

Lud’s Church is sometimes cited as the inspiration for The Greene Chapel in the medieval poem Sir Gawain and the Green Knight. Read the poem however and the mysterious chapel turns out to be a grassy burial mound well north of the Mersey. It is true, though, that the anonymous author hailed from this region and many evocative local place names, such as Wildboarclough, find echoes in the poem.

Castle Cliff Rocks

by

Castle Cliff Rocks is in effect the last formation of the Roaches, though we are many metres below the heights of the escarpment. A brief clamber on a few of these boulders is fun and will help you appreciate why the Roaches is a mecca for rock climbers. Please do take care here, however, especially in wet or icy weather.

This type of rock doesn’t crumble easily and offers a firm grip. Officially known as Roaches Grit, it is very hard sandstone. It formed from coarse sand washed down into a huge river delta during the late Carboniferous period, some 320 million years ago. This rock is a subdivision of the famous Millstone Grit found widely across the Peak District.

The stack here has survived because this is a particularly hard section of rock. It has withstood the eroding efforts of rain, ice and wind much better than the less durable material which must have once surrounded it.

Gradbach Mill

by

This impressive mill was constructed in 1785 for spinning silk. No silkworms ever lived around here – the climate is way too cold for them – but silk manufacturing was a well-established industry in this area. The town of Macclesfield, only six miles away, was the big regional centre and a few, even larger eighteenth century mills also survive there.

The raw material was imported from sunny Italy. Though there were no silkworm cocoons hanging from the trees, what this spot did have was all that free power in the tumbling waters of the Dane. The mill harnessed the river’s energy through a gigantic water wheel. This natural water source made the mill cheap to run, but in the end Gradbach was too remote to be commercially viable. It closed in 1885.
