Linn (geology)

In Scotland and northern England, a Linn is a geographical water feature, a watercourse that has cut through a shelf of hard rock creating a narrow (usually), steep-sided crevice (fracture) through which it runs.

The photograph of the Linn of Dee illustrates the attributes of a typical 'Linn'.

In Gordon (1925) the author describing a walk down Glen Avon in the Cairngorms mentions two Linns on the River Avon - first: A couple of miles below Faindouran Lodge the A'an is spanned by a bridge.

Here the river is narrow, with foaming rapids and deep pools where salmon lie of a September day.
