Relict rock glaciers, slope failure deposits, or polygenetic features? A re‐assessment of some donegal debris landforms

Large-scale debris landforms on the quartzite mountains of north-west Donegal were previously interpreted by the author as relict protalus rock glaciers and protalus ramparts. Re-assessment of these features and their adjacent terrain indicates that slope failures may have supplied much, if not all, of the debris. Implications arising from this recognition that other processes were involved in landform development are discussed and consideration is given to resolving the issue.
