Sinuous Ridge in Gale Crater

These two images were acquired with different look angles to make a stereo pair. Use your red-blue glasses to view the stereo anaglyph.

This scene covers a region of the floor of Gale Crater to the east of where Curiosity landed, providing regional geologic context to understand the broader-scale geologic history. The sinuous ridges towards the bottom (south) end of the images are of special interest, as these may be former river channels.

The relief is inverted because gravels or alteration made the floor of the channel more resistant to erosion. A closeup image shows a part of this ridge at full resolution.

This is a stereo pair with ESP_030748_1750.
