The mountain range that originates in the Andes is the Rocky Mountains. The Andes, stretching along the western coast of South America, are the longest continental mountain range in the world, while the Rockies begin in Canada and extend into the United States. These two mountain ranges are significant for their biodiversity and natural beauty. The Andes are well-known for their high peaks, like Mount Aconcagua, the highest in South America, whereas the Rockies are renowned for their stunning national parks, such as Rocky Mountain National Park in Colorado.
