Denali has the greatest relief of any mountain on Earth, and so represents an important exception to the glacial buzzsaw hypothesis... The height is due to the strength of the granites it is made from, and uplift due a bend in the Denali Fault (which has also moved Denali from ~200 miles further east since it started rising about ~5 Ma).
Some additional GoogleEarth resources for Denali:

The 3rd November, 2002 Denali Fault earthquake was actually ~100 km east of Denali. Resources for this include a comprehensive multimedia gallery and a surface rupture map available in various formats.
