Final answer:
The country with features like the Coast Range, Canadian Rockies, Jasper and Banff National Parks, and the Columbia Icefield is Canada. This nation's western topography includes a variety of mountain ranges that contribute to its diverse landscapes and rich natural resources.
Step-by-step explanation:
The country you are asking about with the Coast Range, Mount Waddington, temperate rainforests, the Canadian Rockies, and the border between British Columbia and Alberta, and landmarks like Mount Robson and Mount Columbia, is Canada.
Canada's rugged topography along the western edge is defined by the massive Rocky Mountains extending to Northern Canada and includes the Columbia Icefield and the Athabasca Glacier. This region is also home to spectacular national parks such as Jasper, Banff, Kootenay, Yoho, and Waterton National Parks.
Along with the Rocky Mountains, the Western Cordillera spans a significant portion of western Canada. The Saint Elias Mountains, part of this range, are notable for their impressive elevations. In contrast, Quebec's Notre Dame Range and Newfoundland's Long Range are extensions of the Appalachians. Together, these various mountain ranges form a diverse ecological and geological landscape that is integral to Canada's natural beauty and resources.
