What is "criffel"

Criffel is a hill in Dumfries and Galloway, south-west Scotland. It is 570 metres high but appears higher because of its great isolation and high relative height — it is the eighth most prominent hill in southern Scotland. It is a prominent feature in many of the views from the northern Lake District on a clear day. It is surrounded by a host of satellites, including Long Fell, Maidenpap and Bainloch Hill. The slopes of Criffel feature the upland vegetation of heather, bog cotton and blueberry and are inhabited by skylarks. Loch Kindar sits at the foot of the hill.
