In reply to a13x:
However, be wary of deleting crags that you regard as collections of crags. The system works better with slightly larger crags separated by dividers (which can have their own location).
As a general rule, crags/buttresses approached from a single parking spot can often be listed as single crags with dividers. There are obviously exceptions to this but please avoid making lots off small crags/ buttresses with only a handful of routes on each.
