Layered Sediments in Terby Crater

This observation shows part of a large region of layered rocks in Terby Crater, in the
southern highlands of Mars. The layers show variation in thickness, brightness, and
color, suggesting a diverse history. Sedimentary rocks on Mars are often relatively lighttoned.
At this site both light and dark materials are visible. Light outcrops are exposed
in many places, particularly in the sides of the large mesas in this area. Light and dark
layers alternate at some levels.
