Summary:
"The Quttinirpaaq National Park region is mountainous including the highest peak in eastern North America. Glaciers cover about half of the map area, including unique floating ice shelves along the north coast, which have largely broken up in the last few decades but many fiord and valley glaciers still contact the sea. Sedimentary rock outcrops form the dominant surficial unit, including large areas of frost shattered rubble mantling broad summits and slopes. Glacial debris is also widespread normally forming a thin discontinuous veneer of till or as isolated erratic boulders. In the past, as now, the main source of run-off and sediment is supplied by glacial meltwater. Consequently most of the unconsolidated sediment lies within formerly glaciated valleys and coastlines where there are complex associations of moraines, glaciofluvial and glaciomarine deposits related to the advance and retreat of valley glaciers and ice caps, coupled with falling sea levels caused by postglacial crustal uplift"--Abstract.
