A Walk From Micklebring to Clifton

 

A view of Beacon Hill in Clifton from Micklebring

After spending a couple of hours at the Save Our Green Belt Coffee Morning, talking with various people potentially affected by the Whitestone 1 Solar Farm at Conisbrough Parks, my friends Lindsey and Pete gave me a lift to Micklebring where they showed me the Millennium Viewpoint, which has a toposcope that show places of interest in the landscape. 

 

The Millennium Viewpoint

 

Set on the Magnesian Limestone escarpment, although it does not provide a good view of the western part of Conisbrough Parks to the north of the M18 motorway, where the bulk of the 327 hectare solar farm is proposed, the prominent local landmark of Beacon Hill and its television masts can be clearly seen.

I was interested to see a dry valley a short distance to the north, which formed the head of The Brook, a stream that flows northwards across Conisbrough Parks and joins Kearnsley Brook, which is joined by Den Brook and then culverted under Sheffield Road and Low Road, before flowing down to the River Don.

The area known as Five Lane Ends in Conisbrough is in a medium risk flood zone, which residents fear will be exacerbated by runoff from the solar panels and, looking at the topographic map of the area, the drainage pattern of the above mentioned brooks is well established. 

 

The topography of Conisbrough Parks

 

Conisbrough Parks is essentially underlain by impermeable mudstones of the Pennine Upper Coal Measures Formation above the Ravenfield Rock and a Google search with the question “do industrial scale solar farms cause drainage problems where underlain by impermeable rocks?” suggests that residents’ concerns may be justified – although a hydrologist experienced in such matters needs to be consulted.

 

The geology of the area around Conisbrough Parks

 

Leaving Lindsey and Pete to get on with the rest of the day, I walked up Greaves Sike Lane and, from a higher elevation, I had a better view of the agricultural land below the Magnesian Limestone escarpment at Clifton, which would be covered by solar panels to a point that is only just over 500 metres to the west of the village.

Continuing to the Grade II Listed C17 Manor House, which I photographed for the British Listed Buildings website, I was about to take the public footpath to Clifton when I bumped into a couple who was coming the other way.

During a long impromptu conversation about Conisbrough Parks and the proposed solar farm, like most people that I had spoken to, we agreed that brownfield sites and roofs on industrial buildings and warehouses would be much more appropriate than building them on unspoiled farmland.

Passing under the motorway, I had panoramic views of the productive arable fields that stretch from the limestone escarpment westwards as far as the eye can see. I found it quite incredible that anyone would think that it is a good idea to cover this land with solar panels that are said to be as high as a double decker bus.

Continuing along the public footpath, I looked back to the south-west to take in the panoramic views of the escarpment at Micklebring that I just left and those to the west. The Whitestone proposals have since been strongly objected to by every MP in South Yorkshire whose constituents might be affected - except for Ed Miliband with his Net Zero policy - for the proposed scale, loss of amenity and wildlife value and negligible benefits to the local communities.

Earlier in the day at the Ruddle Centre, I had seen a display of the remains of a Romano-British villa that had been discovered at Conisbrough Park Farm, which received Scheduled Monument status later on in the year. It makes me wonder how many more archaeological finds are still to be made, to add to those currently marked on the Heritage Gateway map.

Ascending the Magnesian Limestone escarpment, I walked along the footpath towards the centre of Clifton village, which runs along the side of a ploughed field and, as I had seen during very many walks where the underlying bedrock is the Permian Cadeby Formation, Mid-Pleistocene glaciofluvial pebbles are scattered in the soil.

Before going to have a look at the historic architecture in Clifton, which during a visit to The Crags at the beginning of the month I had been told contains a lot of reddened sandstone, I took in the panoramic views of the landscape, which are as good as any I have seen along the Magnesian Limestone escarpment in Doncaster and Rotherham.

Save Our Greenbelt in Braithwell

 

An invitation to a Coffee Morning by Save Our Greenbelt

At some time in autumn 2024, I received some information about the proposed Whitestone solar farms in South Yorkshire in the post, but it was so vague that I didn’t take much notice of it, until a couple of days after my exploration of Darnall Cemetery, when a good friend from Micklebring asked me to help Save Our Greenbelt to fight the proposed Whitestone 1 Solar Farm planned for Conisbrough Parks - in my capacity as a geologist.

 

The Whitestone 1 Solar Farm Masterplan as at July 2026

I don't have the knowledge or experience of the drainage and flooding problems that have been anticipated, due to the run off from the array of solar panels, and I therefore advised that the input of a hydrologist would be required, but also that my experience of producing the Doncaster Geodiversity Assessment for Doncaster MBC with the British Geological Survey might be of use. 

 

The Doncaster Geodiversity Assessment

As part of the Local Development Framework, which Doncaster MBC were beginning to prepare, the implementation of Planning Policy Statement 9: Biodiversity and Geological Conservation (PPS9) place equal weight on biodiversity and geodiversity. 

 

An extract from the Doncaster Geodiversity Assessment

Threats posed by inappropriate site development (or the infilling of quarries), which would not be tolerated in wildlife or archaeological sites of comparable scientific or educational value, now need to be taken into account and this not only includes individual sites but also the geomorphology and landforms too – of which the Magnesian Limestone escarpment that runs from the north to the south of Doncaster is a very important example. 

 

An extract from the Doncaster Geodiversity Assessment

Although the geomorphology and landforms were not specifically highlighted in the Doncaster Geodiversity Assessment, the Magnesian Limestone escarpment and the Don Gorge are topographic features that have greatly influenced the history of the borough, including that of Conisbrough Parks. 

 

A Coffee Morning at the Ruddle Centre in Braithwell

I therefore decided to attend the Save Our Greenbelt coffee morning at the Ruddle Centre in Braithwell, before getting a lift to Micklebring from my friends and then walking to Conisbrough via Clifton, which would give me an insight into how the solar farm would affect this area.

To give me a bit of background to the Whitestone proposals, I looked at their website only to see a map that was so small that I had to use my hand lens on the computer screen to try and find the places that would be affected, which didn’t leave a very good impression on me.

Furthermore, when trying to find Clifton and its Conservation Area on the Doncaster Heritage Map, I was astounded to discover that the proposed solar farm is underlain by a zone that is described as “Major archaeological objection to the development of the site”.

A Walk From Darnall to Attercliffe

 

The aqueduct on the Sheffield and Tinsley Canal

Just before leaving Darnall Cemetery, where I had photographed the Commonwealth War Graves Commission headstones and found some unusual headstones made with various stones, I had a quick look at the sandstone used to build the north-western boundary wall. 

 

A dry stone wall made with flaggy sandstone in Darnall Cemetery

 

In one place very thinly bedded flaggy sandstone has been laid as a dry stone wall, which is a characteristic of the Brincliffe Edge (Greenmoor) Rock and to a lesser extent the Penistone Flags, both of which are Pennine Lower Coal Measures Formation sandstones. It is extremely unlikely that this would be brought in for a dry stone wall, but I don’t ever recall seeing other walling like this in this part of South Yorkshire and its source is a bit of a mystery. 

 

The geological map of the area around Darnall and Attercliffe

In the area around Darnall and Attercliffe, unnamed sandstones from the Pennine Middle Coal Measures Formation (PMCMF) provide the underlying geology and another section of the wall is built with more massive plane bedded sandstone, which is essentially grey with some iron staining. It is similar to the sandstone seen in the boundary wall of St. Lawrence’s churchyard and along Bawtry Road in Tinsley, which is again underlain by an unnamed PMCMF sandstone.

I then set off along Darnall Road past the Ball Inn and the former Darnall Road Board School to undertake my British Listed Buildings Photo Challenge, which consisted of 6 brick built industrial buildings that formed part of the various steelworks that once operated in Darnall, but have very little interest to this Language of Stone Blog.

 

The listed buildings on my Photo Challenge

The former Sanderson's Darnall Steelworks and Don Valley Glassworks on Darnall Road, which is a Scheduled Monument, contains four Grade II listed buildings comprising two sets of crucible steel shops (1871 and 1872), the former offices (c.1872) and the lodge, weighbridge cabin and boundary wall (c.1872).

 

Listed buildings at the Sanderson's Darnall Steelworks

 

Continuing down Darnall Road, the Grade II listed workshop (1913) at the Darnall Works was the next building on my list. It is an example example of a steel framed structure with glass and brick infill panels and concrete dressings, with a corrugated iron roof, but to my eye doesn't possess great architectural merit. 

 

The workshop at the Darnall Works

Although not on my list, I took a couple of general record photos of the aqueduct and adjoining raised footways that form part of the Sheffield and Tinsley Canal, before retracing my steps and heading along Allende Way to Coleridge Road, to find the last building on my Photo Challenge. 

 

The aqueduct on the Sheffield and Tinsley Canal

The crucible steel melting shop (c.1890), now a store, was built for Huntsman and Co. which had associations with Benjamin Huntsman, the inventor of the crucible steel making process, whose tomb can be found in the graveyard of Attercliffe Chapel. 

 

The crucible steel melting shop

Walking down to Pothouse Bridge, I was quite surprised to see that the boundary walls on both sides of the road are built with sandstone similar to the massive stone seen in the walls of Darnall Cemetery. Except for window cills and heads, red brick is used for all of the industrial buildings and associated housing that I had seen and several brickworks in the area are marked on the old Ordnance Survey maps.

Although the brick pits would be mainly extracting the mudstone, the associated unnamed sandstones would presumably have been good enough to use for boundary walls in the immediate vicinity such as this, because the transport of stone adds significantly to its cost. 

 

Crozzle topping a boundary wall

 

As is very commonly seen in Sheffield in the boundary walls of later Victorian houses, one of the walls is topped with a type of slag known locally as crozzle, which was formed during the cementation process of making steel. 

 

The aqueduct on the Sheffield and Tinsley Canal

 

Having completed my Photo Challenge, I completed my walk by walking along the canal towpath back to Attercliffe, with my first stop being the aqueduct that I had seen 20 minutes earlier. As with many other civil engineering projects in Sheffield, such as the Wicker Arches, it uses the coarse grained and often pebbly Chatsworth Grit from the Rivelin Valley. 

 

Supports on the Shirland Lane Bridge

Continuing along the towpath to the Shirland Lane Bridge, I stopped briefly to have another look at the PMCMF sandstone that forms its foundations, where the same colouration as in the boundary wall on Coleridge Road can be seen. 

 

PMCMF sandstone beneath Shirland Lane Bridge

 

I had found this in April 2021, when investigating the Dunsil Coal and associated Coal Measures strata a little further along the canal and just took a few photos before leaving the towpath at Pinfold Bridge and walking to Attercliffe Road, where I caught a bus to Sheffield.

An Exploration of Darnall Cemetery

 

The headstone of William Cheetham and family

My search for the 13 Commonwealth War Graves Commission (CWGC) headstones in Darnall Cemetery had taken just over 20 minutes but, as a geologist with specialist interests in building stone, I wanted to find other interesting headstones and monuments. 

 

The memorial to Samson Chambers

The memorial to Samson Chambers (d.1898) and his wife Eliza Smithurst (d.1913) is built with a pink Peterhead granite base, with the tapering pedestal, capital and urn using a dark grey granite that I presume to be a granite from Aberdeen or the nearby area, with the Rubislaw and Kemnay varieties immediately coming to mind. 

 

A detail of the memorial to Samson Chambers

Although these granites are are part of the Aberdeen and Kemnay plutons respectively, these are both derived from the East Grampian Batholith which formed c.475 million years ago during the Ordovician Period. Both are foliated and contain both biotite and muscovite. The geological memoirs for the areas where they occur, 76E/77W and 77, describe them as having a very similar texture, mineralogy and geochemistry. 

 

Views of the memorial to William Bolsover

The monument to William Bolsover (d.1890) is made with a similar granite, with pink Peterhead granite used for colonnettes. As seen in many Victorian banks, very often in conjunction with Peterhead granite. Rubislaw granite tends to have a much higher biotite content and is darker than Kemnay granite, which has a slightly pink tinge to its alkali felspar, and I think it has been used for both of these memorials. 

 

The headstone of Geoffrey Osbourne and his parents John and Marian

 

A lighter grey granite is used for the headstone of Geoffrey Osbourne (d.1958), which also commemorates his father John (d.1978) and mother Marian (d.1984). The rectangular phenocrysts of alkali feldspar are a characteristic of the granites that were once extensively quarried in Devon and Cornwall, which are largely underlain by the Cornubian Batholith. 

 

The headstone of Thomas Foster and his family

 

Gabbro, an igneous rock composed mainly of the minerals clinopyroxene and plagioclase feldspar, is used for the memorial to Thomas Foster (d.1907), his wife and very young children. Apart from the material used, which I haven’t seen very often in headstones of this age, I was very interested in the design of this headstone, with its broken segmental pediment and an urn/finial. 

 

The headstone of Frances and George Chapman

 

I am by no means an expert in cemetery monuments, but I thought that this was quite unusual and the headstone of Frances Chapman (d.1902) and her husband George (d.1907) is also surprisingly ornate and contrasts with the vast majority of the sandstone headstones in the cemetery. 

 

Sandstone headstones in Darnall Cemetery

 

When looking at the headstones in Wardsend Cemetery, Hugh Waterhouse informed me that he thought that the blank headstones, which are very probably from quarries in the Brincliffe Edge Rock around Brincliffe Edge, were supplied to memorial masons in the city, who inscribed and carved in relief as necessary, but Darnall Cemetery has several other headstones that to not have this standard design. 

 

The Parkes, Goddard and Hill headstones

Those of William Ernest Parkes, Beatrice Goddard and William Henry Hill, who all died in 1907, also have an unusual design and the decoration includes colonnettes with capitals, a pediment like feature and decoration with carved ivy leaves and other floriated details. 

 

Headstones with a clasped hands motif

 

The clasped hands motif, seen on the headstone of Harry Goddard, is a feature of the headstones of Elizabeth Stanford (d.1906) and her husband Fred (d.1925) and another where the front face of the stone has delaminated to remove the inscription. Forming a mirror image of each other, the design incorporates a depiction of tree trunks, which have had their branches sawn off, and have a dove holding a leaf in its beak on the top. 

 

The Ramsey and Speddings headstones

 

Carrara marble from Italy has been used for several headstones, including Annie Ramsey (d.1905) and Walter Ramsey (d.1923) and Jane (d.1927), Harold (d.1949) and Doris (d.1989) Speddings. These headstones have been made in the same style, with the Ramsey memorial being weathered to a much greater extent, with much of the detail of the ivy leaves having been lost.

 

A marble headstone that has lost its lead lettering

As with the CWGC headstones in the cemetery, where the Portland limestone has also lost much of its detail, the deep saccharoidal weathering and significant loss of the surface is probably the result of sulphurous pollution from the steelworks in the Lower Don Valley and another marble headstone has lost nearly all of its lead lettering. 

 

The headstone to members of the Nicholson family

Another example of the use of gabbro is seen in the headstone (1919) that commemorates several members of the Nicholson family. Finer grained gabbros are now imported from India and China, but before this South Africa was supplying coarser grained gabbro from the Bushveld Complex, although I don’t know when this was first used in Britain. 

 

The headstone of members of the North family

 

The last headstone that I noted is that of Samuel (d.1891) and Julia (d.1919) North, which I first thought was another use of gabbro but, looking more closely at this, I could see that it is predominantly composed of intergrown crystals of feldspar and that it is a variety of larvikite, which has a colour that I am not familiar with but could be Marina Pearl.
