Lake Greenhow: A Forgotten Relic of the Ice Age
Yesterday’s post led me to glaciers, glacial lakes, and the like. At Botton Head, my imagination ran riot. Difficult as it is to picture now, 10,000 years ago, a glacier covered the Tees Valley before me. The ice sheet, it is well-known, never quite managed to smother the North York Moors. So, naturally, I wondered…

Newtondale: A Gorge Too Big for Its Stream
North Dale sits at the top end of Newtondale, a gorge that stretches all the way to Pickering. Newtondale is an oddity, or so everyone says, because the little Pickering Beck, which now trickles through it, could never have gouged out such a deep, narrow valley. At its tightest points, the valley is only 500…

A Geologist’s Nightmare: Wild Guesses at Dunbar
A fleeting stopover at Dunbar and a wander along the coastline offered up a geological wonder. The rock formation on the shore was arranged, rather whimsically, in red and grey layers, calling to mind a Scooby snack tipped on its side. Of course, not being a geologist, I can only speculate wildly about the rock…

Burn o’Vat
As the world grew warmer at the close of the last Ice Age, powerful rivers coursed beneath the melting glaciers. Boulders and gravel tumbled along these currents, scouring the riverbed with relentless force. The water, under immense pressure, surged through fissures in the harder rock, forming powerful whirlpools akin to a giant plughole. Over centuries,…

Dovedale Griff
On the weather front, a rather dreary day unfolded with the National Trust at Bridestones. Nevertheless, a new view for me as I stood atop one of the High Bridestones, gazing down upon the narrow upper stretch of Dove Dale, also known as Dovedale Griff. Beneath me, the valley slopes will, in a few months,…

Wind, Rain, and the ever-changing Bridestones
The geological makeup of the North York Moors primarily comprises strata of sedimentary rock, deposited beneath the waters during the Jurassic Age. As the Jurassic sea level rose and fell, rocks of various densities were left. Over time, wind and rain tirelessly eroded away at these rocks, reshaping the landscape. Here at the Bridestones, the…

Roseberry Common: Reliving an old training route over the bracken
One of my favourite training routes used to be a circuit around Roseberry Common, where I would carefully choose the best path through the varied terrain. I like to revisit this route before the bracken becomes too thick to navigate. When I look at the Topping from this viewpoint, the dominant colours are those of…

The coastline near Cove
The Berwickshire coastline is a rugged and untamed stretch of land that is a favourite destination of ours for a refreshing break during a northbound journey, offering ample opportunities for exercise and fresh air. These breathtaking views along the coast are the result of millions of years of sedimentary rock formation during the Palaeozoic geological…

Devensian musings
I have mentioned many times of the great Devensian ice sheet which flowed over the Pennines at the Stainmore Gap, spilling out into what would become the Vale of Cleveland. And it is also common knowledge that the glacier did not flow over North York Moors, which became an island in a sea of ice,…

Kildale
An autumnal morning. Once the cloud had dissipated, the top of Park Nab opened up a full view of this interesting valley once flooded, dammed up by the Tees ice sheet. The slight high ground on the valley floor to the left is a terminal moraine and the furthest extent of the glacier. Here marks…
