The Canadian Rockies are a large mountain range in Canada. 


The Canadian Rockies are a huge mountain system in Western Canada. 

These mountains look very different from the American Rockies to the south. The Canadian peaks are often very jagged and sharp. This happened because huge sheets of ice, called glaciers, carved the land. These glaciers made wide, U-shaped valleys between the peaks. 
Many famous mountains rise high above the clouds here. 
Water is a very important part of this landscape. The Rockies act as a divide for many river systems. Some rivers flow west toward the Pacific Ocean. Other rivers flow east toward the Arctic Ocean or Hudson Bay.
People have long visited and worked in these mountains. Building the Canadian Pacific Railway was a very hard job. Workers had to cross steep passes and fast rivers to link the provinces. Today, much of this beautiful land is protected in national parks.
The Canadian Rockies are a major mountain system located in Western Canada. 

Geologically, the Canadian Rockies are defined by their unique composition. They are made primarily of layered sedimentary rocks. These include limestone and shale. This differs from the American Rockies to the south. The American ranges consist mostly of metamorphic and igneous rocks like granite and gneiss. The Canadian peaks appear more jagged than their southern neighbors. This is due to heavy glaciation. Glaciers have carved the landscape into sharply pointed mountains. They have also created wide, U-shaped valleys. In contrast, the American Rockies have more rounded peaks and V-shaped valleys carved by rivers.
The range is divided into two main groupings. These are the Northern Rockies and the Continental Ranges. The Northern Rockies include the Muskwa and Hart Ranges. The Continental Ranges are subdivided into three parts. These are the Front Range, the Park Ranges, and the Kootenay Ranges. The division between the two main groups occurs at Monkman Pass. This pass is northwest of Mount Robson. The McGregor River valley and the Kakwa River valley also separate these regions. 
Several high peaks define the skyline of the Canadian Rockies. Mount Robson is the highest peak in the range. 
The mountains serve as a vital water source for the continent. They form a divide between different drainage systems. Water on the west flows toward the Pacific Ocean. Water on the east flows toward the Arctic Ocean or Hudson Bay. Many major rivers originate in these mountains. These include the Fraser, Columbia, North Saskatchewan, Bow, and Athabasca Rivers. Interestingly, only the Peace River actually penetrates the mountain range itself. The climate here is cooler and wetter than in the south. This leads to moister soil, larger rivers, and more glaciers.
Human history in the region includes significant engineering feats. The Canadian Pacific Railway was founded to connect British Columbia to eastern provinces. Building this railway was a massive challenge. Workers faced treacherous mountain passes and fast rivers. They also had to deal with sheer drops during construction. Today, much of the area is protected for its natural beauty. Five national parks are located within the Canadian Rockies. Four of these are adjacent: Banff, Jasper, Kootenay, and Yoho. 
Conservation efforts have helped preserve these unique landscapes. In 1984, a group of parks was declared a UNESCO World Heritage Site. This includes the four adjacent national parks and three provincial parks in British Columbia.
