Hallstatt, Austria
Earth Hallstatt, Austria
Human activity around Salzkammergut, Austria, began in prehistoric times, with the salt deposits being exploited as early as the 2nd millennium B.C. This natural resource formed the basis of the area's prosperity up to the middle of the 20th century, a prosperity that is reflected in the fine architecture of towns like Hallstatt.

Snow-topped mountains are clear in this image from the Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER) on NASA's Terra satellite. The salt deposits are underground and not seen here.
