The minor road around 53.95649 N, 2.562218 W (use Google Maps or Earth) passes through the Trough of Bowland. Like everywhere in England, it's not a long way from civilisation in these days of motor transport, but if you're not wary sudden changes of weather can kill you just as dead as in the Alps or Andes.

The Forest of Bowland is one of those areas that weren't easily accessible to ordinary folk until fairly recently, being private grouse moors. Look up "Manchester Rambler" and "Kinder trespass".

It's not a dale because those are in Yorkshire or Derbyshire :}
It's nearer a clough (pron. cluff) which is a steep narrow valley.
