Ungava Peninsula
Remote Quebec peninsula, ancient ice sheet centre, Inuit homeland.
The Ungava Peninsula is the far northwestern part of the Labrador Peninsula of the province of Quebec, Canada. Bounded by Hudson Bay to the west, Hudson Strait to the north, and Ungava Bay to the east, it covers about 252,000 km² (97,000 sq mi). Its northernmost point is Cape Wolstenholme, which is also the northernmost point of Quebec and any province of Canada. The peninsula is also part of the Canadian Shield, and consists entirely of treeless tundra dissected by large numbers of rivers and glacial lakes, flowing generally east–west in a parallel fashion. The peninsula was not deglaciated until 6,500 years ago (11,500 years after the Last Glacial Maximum) and is believed to have been the prehistoric centre from which the vast Laurentide Ice Sheet spread over most of North America during the last glacial epoch.

Lore & Background
Geologically, the Ungava Peninsula is situated on the northeast portion of the Canadian Shield where the Rae Province connects with the Superior Province. The region is composed of Archean rocks (ca. 2.7–2.9 Ga) from the Douglas Harbour Domain. These are overlain by Paleoproterozoic supracrustal sequences (ca. 1.8–2.1 Ga) and intruded by Paleoproterozoic diabase dykes (ca. 2.0–2.2 Ga). The supracrustal rocks comprise nappes that form part of the Ungava and Labrador troughs. U–Pb isotope analyses of zircon yield secondary ages around 1790 Ma, interpreted as the age of metamorphism from a probable continental collision. The Pingualuit impact crater is located on the peninsula. The extinct Ungava brown bear, a population of the grizzly bear, is named after this peninsula, as is the Ungava seal, a subspecies of the Harbor seal.
Reader's Guide
The Ungava Peninsula holds significance as both a geographic and historical landmark. Demographically, it has an estimated population of 10,000 inhabitants, 90% of whom are Inuit, living in 12 villages spread along the coast. The largest village, Kuujjuaq, is the capital of the Kativik Regional Government, which includes all of the peninsula. The peninsula's offshore islands are part of the Nunavut Territory. The region is accessible by air services, with links to southern Québec, and seasonal shipping when sea-ice breaks up. Thick permafrost prevents the use of conventional building techniques in some areas. The climate is extremely cold (Dfc in the Köppen climate classification) because the Labrador Current keeps the region (and all of northern Québec) colder in the summer than other regions at comparable latitudes. The peninsula was not deglaciated until 6,500 years ago (11,500 years after the Last Glacial Maximum) and is believed to have been the prehistoric centre from which the vast Laurentide Ice Sheet spread over most of North America during the last glacial epoch. The Unavuk Peninsula is part of the Nunavik proposed autonomous area of Quebec.

Frequently Asked Questions
What is the Ungava Peninsula?
It is a vast landmass forming the far-northwestern tip of the Labrador Peninsula in Quebec, Canada. Bordered by Hudson Bay, Hudson Strait, and Ungava Bay, it spans roughly 252,000 square kilometres of remote Arctic terrain.
Who lives on the Ungava Peninsula?
About ten thousand people reside in this isolated region, and roughly 90 percent of them identify as Inuit. The largest settlement in the area is the village of Kuujjuaq.
What is the Ungava Peninsula famous for geologically?
Scientists regard this area as the original nucleation centre from which the enormous Laurentide Ice Sheet spread outward across most of North America during the last glacial period. That ancient glacial origin shaped the peninsula's distinctive bedrock landscape.
What is the northernmost point of the Ungava Peninsula?
Cape Wolstenholme sits at the very tip of the landmass and holds the distinction of being the northernmost point not only of Quebec but of any Canadian province.
Why is the Ungava Peninsula important?
It is one of the most remote and thinly populated stretches of land in Canada, yet it plays a key role in understanding continental-scale glaciation. Its Inuit communities also sustain cultural traditions in one of the harshest Arctic environments in the country.
