The western border of this region is made up of high land between Quebec and Labrador. The east is bound by the Labrador Sea. Northern Labrador is mostly made up of mountains. The highest peak is the Torngat range. It rises to over 1525m above sea level.
Most of northern Labrador is made up of tundra plants and barren rock. The past work of glaciers can be seen in the peaks and fiords. Valleys are broad and deep. Glacial till is found at the bottoms of these valleys. Forests have grown up from the soil left behind by glaciers.
Winters are very cold. January temperatures at sea level average –18° C. Summers are short with a few warm days. The temperature around the coast often falls to around 6°-10° C. The southern part of this region is slightly warmer. Yearly precipitation is light (46–70cm). Half of this falls as snow. The northern Labrador coast is blocked by pack ice from December to June.
