#122: Limestone of the Westmorland Dales

Countrystride

...in which we set out from springtime Orton to explore the limestone scars of the Westmorland Dales in the company of husband-and-wife geologist / botanist team Syvia and Peter Woodhead. Alongside bubbling Chapel Beck, we encounter early flowers and a lively March hare as we learn about the geological origins of limestone - in distant coral seas some 350 million years ago. Arriving on Orton Scar, with its big-sky panoramas, we reflect on the industrial processing of lime – for agriculture and construction – and observe the 'lasagne' layering of different eras of deposition. Passing limestone pavement on the shoulder of Knott – grikes forming micro-climates for an abundance of rare plants – we encounter myriad fossils, of corals, gastropods and sponges, that record cycles of life and mass extinction. Chased by a storm that never arrives, we finish our walking circuit at Gamelands Stone Circle, where we reflect on the power and legacy of ice.
