Did you know that the Rocky Mountains are more than three thousand miles long and span both the United States and Canada? Learn more about these majestic mountains in this book for young readers! The Rocky Mountains are split into four groups: the Canadian and Northern Rockies, the Middle Rockies, the Southern Rockies, and the Colorado Plateau. Seven different national parks across the United States and Canada have parts of the Rocky Mountains within their borders, including Rocky Mountain National Park in Colorado. Thanks to the vast distance the mountains cover, the land is home to a wide range of wildlife including grizzly bears, mountain goats, great gray owls, snakes, lizards, and prairie dogs. For thousands of years, the majesty of this mountain range has dazzled those who call it home, from First Nations to European explorers, and those who live there today.
