(DESCRIPTION)
Text, Tin Bider, Algeria
 
In the high desert of Algeria, at the southern end of a range of hills, is a 4-mile-wide impact crater called Tin Bider.
 
Tin Bider is a complex impact crater with several concentric rings that formed terraces as rock collapsed after the impact.
 
A lack of rainfall in this high desert environment has helped preserve the intricate terraces of this 70-million-year-old crater.
