No, the Alaska Range is not part of the Rocky Mountains. While both mountain ranges are part of the larger system of North American mountain ranges, they have distinct geological histories and characteristics.
The Rocky Mountains, often simply called the Rockies, stretch from Canada down into the southwestern United States. They are primarily formed from ancient sedimentary rock that has been uplifted due to tectonic activity.
On the other hand, the Alaska Range is located in Alaska and includes some of North America’s highest peaks, such as Denali (formerly known as Mount McKinley). This range is primarily composed of volcanic and metamorphic rock, which differentiates it from the Rockies.
Hence, while both ranges share a geographical and ecological context in North America, they are separate entities within the vast landscape of the continent.
