HIPOD: Wrinkles in Rock

The bedrock in this region of Arabia Terra has been worn away by the wind, revealing their internal structure and geologic history.

The wavy lines are individual layers of sand and dust, originally laid down as the bedrock was forming. These patterns indicate that the bedrock formed as layers of sand and dust lost their confrontation with the relentless Martian wind in a desert-like environment.
