The Labrador Peninsula is covered by the Laurentian Plateau (or Canadian Shield), dotted with mountains such as Otish Mountains. The Ungava Peninsula is notably composed of D'Youville mountains, Puvirnituq mountains and Pingualuit crater. While low and medium altitude peak from western Quebec to the far north, high altitudes mountains emerge in the Capitale-Nationale region to the extreme east, along its longitude. In the Labrador Peninsula portion of the Shield, the far northern region of Nunavik includes the Ungava Peninsula and consists of flat Arctic tundra inhabited mostly by the Inuit. Further south lie the subarctic taiga of the Eastern Canadian Shield taiga ecoregion and the boreal forest of the Central Canadian Shield forests, where spruce, fir, and poplar trees provide raw materials for Quebec's pulp and paper and lumber industries. Although the area is inhabited principally by the Cree, Naskapi, and Innu First Nations, thousands of temporary workers reside at Radisson to service the massive James Bay Hydroelectric Project on the La Grande and Eastmain rivers. The southern portion of the shield extends to the Laurentians, a mountain range just north of the Saint Lawrence Lowland, that attracts local and international tourists to ski hills and lakeside resorts.
