  This is an image generated from 2'x4' orthometric (above mean sea level)
heights covering the state of Alaska and surrounding areas. Some
interesting features to note about this image are:

  The large area of mid/high altitudes (green/orange/red) is the Northwest
tip of the Rocky Mountains, transitioning into the Alaska Range.  Notice also
that the Rockies contain significant high-frequency information which have 
similar high-frequency effects upon the geoid.  Although not prominently
visible, Mt. McKinley (at 20,320 feet, the highest point in North America)
is located in the Alaska Range (Latitude ~63N, Longitude ~209E).

  The E/W mountain range in the North of Alaska is known as the Brooks
Range.  Apart from the Rockies/Alaska Range, this range has the largest 
terrain-induced impact on the geoid in the area.
