. However, there is little direct evidence for dating the exploitation of iron ore from scowles.English Heritage — Scowles Survey
/ref> The most likely origin of the word "scowle" is that it derives from a Brythonic word ''crowll'' meaning a cave or hollow, or the Welsh word ''ysgil'' meaning a recess. Welsh was the main language in the area before about the 9th century.

Characteristics

Types of scowle range from deep irregular quarry-like features to amorphous shallow hollows. Shallow depressions could be either scowles which have been backfilled, or could represent subsidence of the ground surface above old mines or natural caves. Small pits with mounds of spoil associated with them probably represent different types of iron ore extraction in the vicinity of the exposed cave system, or people prospecting for iron ore away from the main deposits. Small circular pits without associated mounds might represent natural geological features. Ecologically, scowles are now recognised as important wildlife habitats, being home to lower plants and ferns, bats and invertebrates. However, some are threatened by illegal dumping and
