The Rocky Mountains are a large group of mountains on the North American continent（洲）. The Rockies are found in the western part of North America. They stretch（连绵）from Canada in the north to the United States in the south. The southern part of the Rockies ends in the state of New Mexico.

The Rockies are the longest mountain range in North America. They have many high peaks（山峰）. The highest is Mount Elbert in Colorado. It is three miles high.

In the summer, the Rockies are warm and dry, though it does rain sometimes. During the winter, the weather is wet and cold. Heavy winter snow falls in the higher parts of the Rockies.

Many people like to visit these mountains. They ride bikes, hike on trails, ski, or fish. A special area called Rocky Mountain National Park is in Colorado. The national park is reserved（留出）for people to visit. Visitors to Rocky Mountain National Park can see the wild animals that live there. These animals include elk（麋鹿）, moose（驼鹿）, mountain goats, and mountain sheep.
