A long,
winding valley of Mamers Valles on Mars ends with a circular depression containing a crater, seen here by the
European Mars Express.
The crater
sits approximately 18.6 miles (30 km) wide and almost 4,600 feet deep (1,400
meters), and Mamers Valles runs about 621 miles (1000 km) long along boundary
between the northern Martian lowlands and southern highlands. Scientists call
regions such as this “fretted terrain” because of the many deep and wide
valleys and circular depressions.
The
location centered at 39 degrees north and 17 degrees east on the planet shows structures
within the dark crater that indicate water may have once flowed there.
