Notes: As Dartmoor is a granite, rather than a Limestone geology, you do not really have caves - however, there are many examples of rocks leaning against one another to produce a cave-like entrance. Not to be confused with 'potato caves' or adits (see ‘tinning’), which are both human constructions. Where a rock has an overhang these are called on Dartefacts 'rock shelters' and often appear to have been used regularly by sheep. 'Windows' and 'Arches' often form as a consequence of a large slab of rock having landed on top of a gap between rocks or perhaps when a large rock ‘falls away’. Windows are smaller and perhaps harder to get too, whereas Arches can usually be walked through fairly easily. Passageways are corridors which occur when blocks of rock allow passage between but don’t possess a slabbed roof - they are not caves as they don’t have a roof. Where a 'chock-stone' has fallen into a gap and and wedged itself, this is called a 'Wedgie' on Dartefacts and is in another classification and not considered an 'arch' or 'window' - although the difference can sometimes be hard to separate!
