A Limestone Pilgrimage
The third section of Gary Hogg’s ‘And Far Away’ concerns a walk from the Dorset Coast to the Cotswolds which is actually just the first section of an envisaged longer route. Mooching about on the beach near Burton Bradstock he recalls the genesis of the idea for the route:
I remembered how I had first conceived the idea, looking up by chance one morning at the geological map hanging on the wall a yard away from the table in the window at which I write. There it was, that butter-cup yellow streak, slanting away across England from the Dorset coast, north-east-by-east, to vanish at the Humber and reappear again for the last few miles on Pickering Moor in Yorkshire.
Here the oolitic limestone is 12 (in pale, rather than buttercup, yellow) Follow this link for another lovely old map in which the oolitic limestone is divided into 2, of which one, the lower oolite, is buttercup-yellow.
When I became sufficiently curious to superimpose another map on the geological map that had attracted me I made the interesting discovery that the old Foss Way, the original Roman road from the Dorset coast to the North Sea Lincolnshire coast, followed this line of buttercup-yellow for a very considerable portion of its 180-odd miles. The legend on the map showed me that the colour in question stood for oolitic limestone. If then I mapped out a walk that used the Foss Way as a line for my left flank to rest on I could follow this limestone across England for as far as I liked to walk.
In fact, the Fosse Way ran from Exeter (Isca Dumnoniorum) to Lincoln (Lindum). And 180 miles seems like a hopelessly inadequate under-estimate. But, let’s not quibble – it’s a lovely idea, which has quite captured my imagination.
