Mt Denali (formerly named Mt McKinley), a dominant peak of the Alaska Range such as Mt Foraker and Mt Hunter are composed of resistant granites. These rocks are not easily worn away by erosion and weathering allowing elevations to remain relatively high compared with other mountains of similar ages.
