From Charles Lyell 22 October 1861
Summary
Ice could not have formed the blockages in Lochaber unless in every case the water escaped over some col into a contiguous valley on the same watershed, or into the eastern watershed. Supposes that the cols were not land-straits, but the places where the lakes were drained when forced to flow the wrong way.
