Abstract

The glaciers of the Torngat Mountains of northern Labrador are the southernmost of the Canadian Arctic and the easternmost of continental North America. Currently, over 100 small mountain glaciers cover an area in excess of ~21 km2 confined mostly to small cirques and upland depressions. This study reconstructs and dates the areal extent of Torngat glaciers during the Little Ice Age (LIA); enabling the first assessment of regional glacier changes over the past several centuries. 165 mapped LIA glacier paleomargins are compared to current (2005) glaciers and ice masses showing a 52.5% reduction in glacier area from the LIA to 2005 with 12 formerly active glaciers having since disappeared.
