This depiction of an area south of San Martin de Los Andes, Argentina,
is the first Shuttle Radar Topography Mission (SRTM) view of the Andes
Mountains, the tallest mountain chain in the western hemisphere. This
particular site does not include the higher Andes peaks, but it does
include steep-sided valleys and other distinctive landforms carved by
Pleistocene glaciers. Elevations here range from about 700 to 2,440
meters (2,300 to 8,000 feet). This region is very active tectonically
and volcanically, and the landforms provide a record of the changes that
have occurred over many thousands of years. Large lakes fill the broad
mountain valleys, and the spectacular scenery here makes this area a
popular resort destination for Argentinians.
Two visualization methods were combined to produce this image:
shading and color coding of topographic height. The shade image was
derived by computing topographic slope in the north-south direction.
Northern slopes appear bright and southern slopes appear dark, as would
be the case at noon at this latitude in the southern hemisphere. Color
coding is directly related to topographic height, with green at the
lower elevations, rising through yellow, red, and magenta, to white at
the highest elevations.
