Grand Teton Range from Landsat
March 13, 2007
The Landsat image above showing Grand Teton National Park (in western Wyoming) was taken on September 23, 2002. The jagged, snow capped peaks of the Teton Range rise to 13,770 feet (4,197 m) -- more than 7,000 feet (2,134 m) above the valley below. Grand Teton National Park was designated as park land in 1929 and expanded to its present-day size in 1950. The perspective of this image was created by merging digital elevation data with a true-color Landsat 7 image. Note that there's no vertical exaggeration on this image. The scenic nature of the Grand Teton's results from erosion of Precambrian crystalline rocks along the steeply dipping Teton normal fault and from glaciers that thousands of years ago gouged out lofted valleys.
