a mountain range in southern Alaska, in the system of the North American Cordilleras. The range is about 1,000 km long, with mean elevations of about 3,000 m. The highest peak in the range and in all of North America is Mount McKinley (6,193 m), around which is the Mount McKinley National Park. The Alaska Range was formed in the Jurassic Age. In the axial part it is composed of intrusive rock (granodiorites); along the edges, of sedimentary rock. The slopes are steep, rocky, and rugged. Railroads and highways have been built through the deep and sometimes rather broad valleys which cut through the Alaska Range. The range is an important climatic boundary. The wet southern slopes are covered by coniferous forest up to an elevation of 800 m and above this level are covered by eternal snows which feed the large valley glaciers. The northern slopes are more arid, with the timber line reaching up to 1,000–1,100 m. Mountain tundra lies above the forests. [1–1478–1 ]
