3. dating of the major glacial lake shore- lines in the George River basin (Nas- kaupi and McLean glacial lakes) and location of other suspected glacial lake systems: 4. determination of the date of final dis- appearance of late-Wisconsin ice in the central region of Labrador-Ungaval5Ja~ 5. It is probable that in response to a change in climate, the Lake Plateau of central Quebec-Labrador developed an ice cap by "instantaneous glaciation", followed by radial outflow. The early influence of an open Hudson Bay in the development and differential expansion of the ice cap towards the west was favoured by (Hare, ) but not on.

CHABLAIS Labradors is owned by Jean-Louis Blais and Madeleine Charest since We are recognized to be one of the best Labradors breeders in the world. We are located in Saint-Gilles, near Quebec City, Canada.
Until recently, one of the most useful cultural surveys of Labrador was David Zimmerly, Cain's Land Revisited: Cultural Change in Central Labrador, (St. John's: Institute of Social and Economic Research, Memorial University of Newfoundland, ). However, Zimmerly's chronology excluded several important early themes of Labrador history. Interglacial-glacial cycles of the Quaternary are widely recognized in shaping phylogeographic structure. Patterns from cold adapted species can be especially informative - in particular, uncovering additional glacial refugia, identifying likely recolonization patterns, and increasing our understanding of species’ responses to climate change. We investigated phylogenetic structure of .

Find more information about: OCLC Number: The glacial geomorphology in Québec-Labrador is dominated by two major glacial landform systems. One is a radial pattern of till lineations, ribbed moraines, and eskers that can be traced inwards from the peripheral eastern, southern, and western parts of Québec-Labrador towards the central part of the by: Central Labrador.
Central Labrador extends from the shores of Lake Melville into the interior. It contains the Churchill River, the largest river in Labrador and one of the largest in hydroelectric dam at Churchill Falls is the second-largest underground power station in the world.
Most of the supply is bought by Hydro-Québec under a long-term y: Canada. An important lobe of central Quebec-Labrador ice probably filled southern Ungava Bay until as late as to BP, accounting for the existence of glacial lakes.

Quaternary Science Reviews Crossref, Google by: In central and southern Labrador, extending to the northernmost Northern Peninsula, glacial features are related to MIS 2 Laurentide glaciation.
Local glaciation influenced the distinctive landscapes of Torngat Mountains National Park, and Mealy Mountains (Akami-Uapishk U. In north-central Quebec and Labrador, the retreating Labrador Ice Dome of the LIS dammed large rivers flowing into Ungava Bay, forming several large glacial lakes (Ives,; Barnett, ; Gray et al., ; Clark et al., ; Jansson and Kleman, ; Dubé-Loubert and Roy, ).These lakes drained when the ice margin retreated sufficiently or became too thin to provide a.
Just after the glacial theory was born, a controversy emerged about the nature of glaciation in Maritime Canada which still resonates today. Was the ice local, originating in upland areas and confined to the land masses, or was the ice part of a great continental ice sheet from Quebec.
A study of rare metal indicator minerals and glacial dispersal was carried out at the Strange Lake Zr – Y – heavy rare earth element deposit in northern Quebec and Labrador, Canada. The heavy miner. The term “washboard moraines” was used by Mawdsley () to describe small, parallel, regularly spaced moraine ridges in northwestern Quebec which were later identified as De Geer's “annual moraines” by Norman ().InH.

[Edward D Derbyshire; McGill Sub-arctic Research Laboratory.; McGill University. Department of Geography.]. Quebec (/ k (w) ɪ ˈ b ɛ k / (); French: Québec ()) is one of the thirteen provinces and territories of Canada.
It is bordered to the west by the province of Ontario and the bodies of water James Bay and Hudson Bay; to the north by Hudson Strait and Ungava Bay; to the east by the Gulf of Saint Lawrence and the province of Newfoundland and Labrador; and to the south by the province of New.

Study Site. Geological History of St. Lawrence River Basin. The Laurentide Ice Sheet was massive and covered millions of square kilometers including a large portion of northern United States and much of Canada.
The massive sheet occurred many times during Quaternary glacial epochs—from ± million years ago to the present. This critical book focuses on the geomorphological landscapes of eastern Canada and provides a companion volume to “Landscapes and Landforms of Western Canada” ().
Labrador and northern Quebec and the magnificent arctic fjords and glaciers. Study of landscapes forms his central focus for understanding of the various areas of. We mapped glacial landforms in one of the two LIS core areas, Quebec-Labrador, in aerial photographs at a scale ofand established the approximate extent of relict landscapes and.
Arctic - Arctic - Terrain: Although the detail of the terrain in many parts of the Arctic is directly attributable to the Pleistocene glaciations, the major physiographic divisions reveal close correlation with geologic structure.
The two largest shield areas, the Canadian and the Baltic, have developed similar landscapes. West of Hudson Bay, in southwestern Baffin Island, and in Karelia the. The early glacial lakes in central Labrador‐Ungava drained eastward along the ice margin into the Labrador Sea, except for glacial lakes Boilay and Gayot‐Delay and high levels of glacial lake Caniapiscau, which drained westward into Hudson Bay.
At a later stage during the deglaciation, drainage was rerouted northward into Ungava Bay. Following the Last Glacial Maximum (LGM) ca. 24 ka (ky cal BP) ago, the LIS began to recede by collapse and iceberg calving 13 (Fig. 1).By ca. 12 ka, the LIS margin stabilized over the. A first lineage (Central lineage, Fig 5), essentially carrying mitotype I, would correspond to the western population subset of mtDNA group #1.
These populations may have originated from a large glacial population located south of the Great Lakes, as previously. Sample locations from Quebec and Labrador give information about the disappearance of ice between 6, years ago (Figure 2).
Certain regions have more samples than others, but data was selected along three transects (within km of the transect) to assess retreat rates along the Western, Central, and Eastern sides of the former.Similarly, another glacial refugium presumably originated in the Appalachian Mountains in the east and then migrated north into Ontario (A3, Fig.
3 & Fig. 4) and possibly Quebec. We predict that with better sampling from (Southern) Quebec, more lineage A3 haplotypes will be found there.
