Boulby Alum Quarries

I needed to unravel a few knots and put some ground under my boots. I was undecided as to where to go…time for the coin. A flip of the coin as to whether it would be moorland or coastal, a second flip to decide on a old favourite on a new site. The outcome, coastal/new.

A while ago I was reading about the Boulby Alum Quarries, I’d never visited the place, I did once try to get there via the the Loftus quarries but failed. I had read that Boulby was one of the best examples of its kind in the country, so that was that, Boulby was the place.

I walked along the Cleveland way to Rockhole, looking for a path into the quarry. All I could find was the trace of a track heading towards Rockhole Hill. I followed the track which got fainter and fainter and took me deep into the quarry. The vegetation got higher and thicker and the track eventually petered-out completely at a large pile of droppings. I’d been following a rabbit track which had led me into a deep thicket of gorse and brambles. I looked for a way forward but couldn’t seen anything that resembled a path.

I had a choice, try and push forward through the quarry or retrace my steps back up to the main footpath and start again. I decided to push on and look for another path. I thought that if I could skirt around Rockhole hill towards the cliff edge I would come across a path, a simple enough plan. The problem was that the foot of the hill and the quarry floor is covered in chest-high rosebay willowherb, bracken, gorse, brambles and boulders, there are also a number of small, steep-sided beck channels concealed beneath the vegetation. The flanks of the hill are steep but less treacherous, they are covered with deep heather and large, impenetrable patches of gorse and brambles. It took me about half and hour of constant scrambling and slipping to cover the short distance to the cliff edge.

Much to my relief, my efforts eventually led to an overgrown track that looked as though it was heading towards the main quarry and alum works. After that it was fairly plain sailing, there were still patches of gorse and brambles to get around but the ground was fairly level and the surrounding vegetation was fairly low.

Moving along the track I began to noticed low walls, the remains of a building, a stone-covered culvert and two beautiful circular stone-lined tanks. The production of Alum started here in the mid 1600s, the Rockhole quarries and structures are the oldest part of the site.

I continued to walk north into the later sections of the works and suddenly found myself standing in the quarry, an amphitheatre of alum, ruins of massive stone walls and heaps of alum shale, facing the sea and backed by the massive sandstone cliffs, a wonderful sight.

The cliffs are never static, large blocks litter the site, some bearing fossils.

Walking around the ruins, the mind starts to wander. It is easy to forget that this was a place of industry and imagine that these are the remnants of a cliff-edge citadel whose myths are still waiting to be discovered.

These cliffs are the highest point on the east coast of our island. The land above the quarry has been occupied for thousands of years, its soils contains the evidence of the district’s earliest house. Archaeologist Steve Sherlock has also found evidence of prehistoric salt production and jet working on the land behind the clifftop, evidence of early industry, albeit on a small scale. Our prehistoric ancestors performed rituals and buried their dead on these clifftops. It is also the location of the famous Saxon Princess burial.

I left the quarries and followed the path that runs between Rockhole Hill and the cliff edge. The track is becoming overgrown, an indication that this site doesn’t see many visitors. A couple of short sections of the path have eroded away, this is not a place for anyone who is nervous of walking along a cliff edge. The track leads back to the Cleveland Way via a couple of lovely tiny woods, shoehorned into the short valleys running down to the cliff tops.

If you are going to visit the quarries I would advise that you avoid following the track down into the Rockhole Quarry, my legs are covered in small cuts, pin-cushioned by brambles and gorse and it took a fair bit of effort to escape the quarry. The cliffs along this part of the coast can be unstable, the track around Rockhole Hill is difficult to find but definitely the one to take, however it is not without danger and should be approached with great caution.

Crossing Peg Powler’s beat

The section of road from Girsby to Over Dinsdale is marked on the OS map as ‘Roman Road’. During the 18th century Gainford Antiquarian, John Cade, studied the Roman Roads of the north and theorised that a Roman road ran from the Humber estuary to the River Tyne. Cade thought that the road may have been an extension of Ryknild or Ickneild Street, a road that ran from Gloucestershire to South Yorkshire. Cade placed the crossing point of the Tees at Sockbridge. The Roman Road became known and is still referred to Cade’s Road.

In the 1920’s Archaeologist OGS Crawford took a look at the area and thought that the crossing point of the was more likely be Middleton One Row at the site of a medieval bridge known as Pountey’s Bridge. A reliable late nineteenth century source reported timber piles and abutments being visible at the site. An earlier report states that a large number of squared Stones being found in the river.

Recent work by the Mid Tees Research Project has discredited Crawford’s theory and moved the search for Cade’s crossing eastwards to a bend in the Tees close to Newsham, where at least three separate river crossings once existed.

The modern road leads to the bridge over the Tees at Low Dinsdale. The bridge was originally built in 1850 by the Surtees family and operated as a toll bridge. In 1955 the bridge was taken over by the North Riding County Council and the original trussed iron beams were replaced with steel beams rolled at the Cargo Fleet Iron Works, a concrete deck was cast then over the beams. The bridge was further upgraded in 1993.

In the churchyard of St John the Baptist at Low Dinsdale is the lower portion of an eleventh century cross shaft. The shaft is carved on all four faces but quite weathered. There are other carved stones within the church but this church is always locked when I visit.
