The Montane Cordillera covers about 461 000 square kilometers of
Canada. It falls between the Pacific Maritime, Boreal Plains, and Boreal Cordillera ecozones and covers most of Southern
British Columbia and some of Southwestern Alberta. The other name for this ecozone is the "Southern Rockies." This ecozone
incorporates some of the inner mountain ranges and valleys of Bristish Columbia such as the Alberta foothills, Okanagan
Valley, and the East and West valleys of Kootenay.
The Montane Cordillera has fluctuating temperatures that move
up and down a lot because of the latitude and different elevations. The winters here are quite normal with moderate temperatures with
an average of -12 degrees Celsius. The summers are also moderate with average temperatures of 15 degrees Celsius. The precipitation
varies greatly due to the elevation and physical aspects of the area, but usually stays between 500 and 1000mm/year. High
elevation areas receive 1200- 2200mm/year, while the driest rainshadow areas receive under 500mm/year. Westerly Winds carry
the moist Pacific air over the mountains and plenty of snow and rain falls as it goes up the windward slope of the Coast Mountains.
As air goes over the eastern slope and enters the ecozone, it is once again warmed as it compresses, causing the clouds to
disappear and a rain shadow over the valleys of British Columbia resulting in extremely dry climates. There is a steady continental
climate throughout the whole ecozone. The air masses moving east create cold, wet, winters, and warm, dry summers. The temperature
greatly varies in each area of the Montane Cordillera. In the alpine region, the average temperature is always under 10 degrees
Celsius. the upper forest slopes have an average temperature under 0 degrees Celsius for 7- 9 months of the year,
while the Ponderosa Pine forests of British Columbia have an average July temperature ranging from 17 to 22 degrees Celsius.
This is a picture showing what the Montane Cordillera looks
like in the season of fall. This is the season when the trees look the most vibrant.
The Montane Cordillera is mostly jagged with many mountains and is part of
the Western Cordillera landform region of Canada. The Rocky Mountains, made up of sedimentary rock, were formed by folding
and faulting, while the Columbia Mountain Ranges, made of igneous and metamorphic rock were formed by volcanoes. The
Coast Mountains, made of mainly igneous rock, were created when the igneous rock beneath the surface of the earth was
uplifted and folded. The Rockies are separated by several valleys, and plateaus. The Columbia Mountain Ranges are steep, rugged
mountans with glaciers. The lava flow from volcanoes before created several deep rivers in this area. The Coast Mountains
is a region covered with forests and has fiords. Fiords are very long bays of sea water with steep sides around it. They were
created when the glaciers which scraped out valleys melted and the sea overflowed the valleys. The mountains have fallen rock
fragments and many rocky outcrops. The rock of the mountain crumbles a lot to form rocky slopes. The Montane Cordillera
has some major river systems within it including the Fraser River, and Columbia River.
