clitter

KLIT-er
A field of broken granite boulders on a hillside — the shattered debris of a tor, spread down the slope below it by frost-heaving and gravity over millennia. Clitter is characteristic of Dartmoor, in southwestern England, where granite tors crown the hilltops and their collapsed remnants litter the slopes below.
Etymology
Possibly from Middle English cliteren (to clatter), or from a dialectal root related to the sound of stones shifting underfoot.
