This enhanced-color image shows a small portion of a dark crater floor in the Tyrrhena Terra region of Mars. This is largely ancient hard bedrock that has been cratered by numerous impacts over the eons.

Two other interesting geological features in Tyrrhena Terra (not pictured here): Herschel Crater and Tyrrhena Patera, one of the oldest volcanoes on Mars.
