The Scar on the Hill: Cliff Rigg Quarry

A dreich veil hung over North Yorkshire this morning, so I look back instead to yesterday, when the sky was clear, the air still, and the sun at least toyed with the idea of shining.

Cliff Rigg Quarry looms above Great Ayton, a cavernous rent in the hillside left behind by an industry that has long sin ...

Echoes from the Old Workings beneath Cliff Rigg

In 1894 the Northern Echo carried a grim report of a inquest into a fatality in a whinstone quarry near Nettle Hole, a place that sits a good fifty metres below any workings that make sense on a modern map. My first thought was that the incident must point towards a tunnel beneath Aireyhol ...

Slacks Wood Quarry And a Stream of Many Names

A dreich morning. Rain, wind and low cloud forced me to keep low, sticking to the woods where I could at least avoid the worst of the weather. This meant I had little choice but to focus on the minutiae. Hence this stream. It cannot even decide on a single name. Near its source on Great Ayton Moor, it is called Howden Gill. Here, in Slacks W ...

On yet another foul day …

... so I didn't venture far; instead, just bagging Roseberry Topping and picking up Cliff Rigg on the way back. Cliff Rigg has a quarry that has been the subject of my posts on several occasions.

This ridge is part of the Cleveland Dyke, a tough volcanic rock that forcefully juts through the much older sedimentary formations surrounding it. Forged some 58 million years ago by a v ...

Late afternoon on Cliff Rigg

A morning spent volunteering alongside the National Trust, cutting sycamore saplings in Cliff Rigg Wood. Not exactly a photogenic opportunity, but later the dog was insistent that we ascend the ridge to bask in the waning afternoon sun. There, the lighting nicely highlighted a strange remnant from a bygone industrial era, the rocky pinnacle once referred ...

A view along the Cleveland Dyke

A view looking down on Gribdale Terrace, a row of white cottages built to accommodate the quarrymen employed at the adjacent whinstone mine and quarry.

The line of the Whinstone or Cleveland Dyke can clearly be seen in the photograph, stretching from Cliff Rigg in the distance to behind the cottages where it follows the line of the road. The presence of the yellow gors ...

An early run taking in the top of the quarry at Cliff Rigg

A super morning, dry and sunny with some noticeable southerly winds. To the west, a large bank of cloud looks ominous but kept its distance.

The quarry, now under the custodianship of the National Trust, is the result of the extensive extraction of Whinstone or dolerite, an extremely hard igneous rock that was ideal for road maintenance. Sandstone w ...
