Site no.: Q21
Site name: Glen Shirra eskers
Grid reference:
Locality: WNW of Loch Crunachdan to the park boundary at Dirc an Uillt Fhearna
GCR Status: N/A
GCR No.: N/A
Type: Natural landforms
Description: A discontinuous ribbon esker extends ENE along the northern side of the divide between Coire Ardair and the Spey. It traverses high above Coire a' Chaorainn and Coire an t-Slugain, linking with a minor channel cut across the col south of Meall a' Chaorain Mór and passing into Dirc an Uillt Fhearna. The meltwaters that passed through this channel laid down several flat-topped mounds, terraces and an esker between it and Loch Crunachan, to the ESE.
Justification: An excellent example of a linked esker and subglacial drainage channel system that links with Dirc an Uillt Fhearna
