Several subglacially formed short flutes show crescentic scours around the boulders at their proximal end and furrows along their sides. The crescentic scours and furrows are partly filled by sorted sand and gravel. and it is suggested here that they were formed by fast flowing, turbulent meltwater in the subglacial cavity where the flute was formed.
