I did a long run with Wor Lass aound the Forest of Dean this morning; I've got a GPS and subscribe to Ordnance Survey maps online; it's easy to create running routes there and upload them to my GPS, but I've found that just because there's a path marked on the map, in reality it might not have been used in years and they're sometimes overgrown with brambles and spiky stuff, which isn't much fun.
Interesting area the FoD though:
Lydney park gardens (we shouldn't have been here, but I know the owners well):
Half the thick green dashed lines on the 1:25,000 of Dartmoor are on the wrong side of valleys/rivers/ridges. And they claim to be the varsity - world leader - in accurate mapping. The effing hoops you have to jump through to meet their data quality spec (ditto UKHO) would bear that out. But then you try navigating on map and compass in the middle of nowhere in pea-souper fog and...
And you still haven't satisfactorily explained why your bird goes running in a lifejacket (she should swap it out for the current standard, by the way. They come with a STASS bottle now)).
A couple of my photographs from another of my favourite walks on Bewick Moor near Wooler .. Not a Mine but another potentially dangerous 'ole in the ground . First time I tried to find this feature , Cateran Hole , I had to use map , compass , distant reference points , pacing * ... now have exact location . Folk lore has it that at one time it went all the way to The Cheviot ... Hi Hi . I have been about 25m in . Certainly not a place to look for when there is snow on the ground or thick mist ...
* ... ETA ... Cateran Hole is still so infrequently visited there is not a well defined track to lead to it from a main track which is about 200m away across Heather , Fern and Gorse .
