This Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER)
image was acquired on July 29, 2000 and covers an area of 30
by 57 km in northern Italy. The false-color image include near infrared, red,
and green wavelengths of light. Lake Garda was formed by glaciers during the
last Ice Age, and is Italys largest lake. Lago di Garda lies in the
provinces of Verona, Brescia, and Trento, and is 51 kilometers (32
miles) long and from 3 to 18 kilometers (2 to 11 miles) wide. The Sarca
is its chief affluent, and the lake is drained southward by the Mincio,
which discharges into the Po River. Many villas are situated on its
shores. On the peninsula of Sirmione, at the southern end of the lake,
are the ruins of a Roman villa and a castle of the Scaligers, an Italian
family of the 16th century. The right-hand image has the land area masked
out, and a harsh contrast stretch was applied to the lake values to display
variations in sediment load. Also visible are hundreds of boats and
their wakes, criss-crossing the lake.
The light tan oval in this image is the floor of a lake in central Italy that has been drained by a tunnel dug through the surrounding hills. Numerous rectangular fields occupy the former lake bottom—now one of the most fertile regions of Italy. The area is still referred to as “Fucine Lake,” even though the lake has been dry for nearly 150 years.
