Floutern Cop is a small prominence above the glacial corrie filled by Floutern Tarn. It is long and narrow. The western end is craggy but the eastern ends tapers away. It looks like it might be a crag-and-tail feature.

This probably doesn't fit with the idea of a corrie glacier but I did read in the autumn that corrie glaciers were the last phase of glaciation in the district.
