A large smooth mass of rock detached from its place of origin; SYN. bowlder.

A steep rugged rock or cliff.
In previously glaciated areas, a large lump of rock that a glacier has been unable to wear away. As the glacier passed up and over the crag, weaker rock on the far side was largely protected from erosion and formed a tapering ridge, or tail, of debris.
An example of a crag-and-tail feature is found in Edinburgh in Scotland; Edinburgh Castle was built on the crag (Castle Rock), which dominates the city beneath. + prikaži više
