|Shropshire Hills – The Lawley from Caer Caradoc with The Wrekin beyond|
Earlier this year I received a commission to write a poem for a hydro-geologist, for his birthday.
I was very glad to be asked, but this in turn made me ask myself:
‘What kind of poem would a hydro-geologist enjoy?’
‘What really excites them?’
and finally ‘What do I know about hydro-geology?’
The only question I could answer was the last one, and the answer was ‘Hardly anything.’ But fortunately Shropshire has more hydro-geologists than you can shake a stick at. There was advice at hand and resources aplenty.
My first port of call was the Geology Gallery at the newly refurbished Shrewsbury Museum and Art Gallery link. I love this museum. It was opened in 2014, and is thoughtfully presented and designed. The Geology Gallery not only has beautiful specimens of rocks and fossils, but also commissioned art and a wonderful video showing the voyage of Shropshire.
It turns out that the reason there are so many hydro-geologists in Shropshire is that it has an extremely diverse range of geological strata both in age and rock type.
Add to that, in the words of the Shropshire Geological Society,
‘its frontier position: at former plate boundaries, just below the major erosion surface of the crust prior to opening of the Atlantic Ocean, and the meeting point of several glaciers during the last Ice Age. Thus the variety of geological settings is unmatched within the British Isles or, within such a relatively small area, probably anywhere else in the world.’ http://www.shropshiregeology.org.uk

Shropshire has, in its 500 million year history, travelled from a location south of the Tropic of Capricorn in the Southern Hemisphere 12,000km to where it is today. In that time it has been volcanic, forested, tropical, desert, shallow seas, and now the temperate landscape of hill and field, a patchwork embroidered with hedge and forest.
Armed with this new information, I walked up one of my favourite hills: The Lawley. Looking south from the Lawley, one sees Caer Caradoc thrusting through an ancient fault line running in Pre-Cambrian rock northwards to the Wrekin. Around the Lawley spreads the intricate complexity of the countryside, rising and falling, growing and dying. Under my feet was living rock, full of the signs and scars of its journey. And growing from it, the most delicate and hardy of flowers, heather, and the lichens, airy and brittle versions of the languid seaweeds fossilised nearby.

Afterwards, it did not take long to write the poem, and then, having heeded the advice of poets in my writing group, I delivered Walking the Hills to the person for whom it was written.
But a little bit like Shropshire, Walking the Hills had further to travel. I submitted it to the WriteScience Poetry Competition poetry of science and it was selected as one of the six finalists. I was sent to the Minton Library in Stoke-on-Trent to read it and celebrate the symbiosis of art and science at their Fun Palace festival. ceramic city
Stoke-on-Trent, aka The Potteries,
was just the right place for the poem to arrive,
a place built on special rock and soil which is made and remade,
heated and cooled, used and discarded.
