The Rocky Mountains are part of the Western Cordillera, one of the largest mountain belts on earth. They stretch over 6000 kilometres from Alaska along the western side of North America right through to Mexico. The mountains are young, having been formed mostly in the last 15 million years, by an oceanic part of a tectonic plate converging with a continent. There is still volcanic activity (Cascade Range) within in the Western Cordillera, which gives an indication of the "young age" of the range. The highest peaks are within the Rockies with Mount MacKinley in Alaska being the highest at 6194 meters.
