United States
The Rocky Mountains, at the western edge of the Great Plains, extend north to south across the country, reaching altitudes higher than 14,000 feet (4,300 m) in Colorado. Further west is the rocky Great Basin and deserts such as the Chihuahua and Mojave. The Sierra Nevada and Cascade mountain ranges run close to the Pacific coast, both ranges reaching altitudes higher than 14,000 feet. The Alaskan Range passes through much of Alaska and is home to Denali which stands at a height of 20,310 ft (6,190 m) above sea level and is the tallest mountain in the United States and in North America. Denali is in fact the tallest mountain in the World on land from base to summit standing at about 18,000 ft (5,490 m), which is about 4,000 ft (1,220 m) higher than Mount Everest which sits at a height of about 14,000 ft (4,270 m) from base to summit.
