Olympica Fossae

Olympica Fossae is a complex channel located on the Tharsis volcanic plains between Alba Mons and Olympus Mons. The sinuosity of the large channel in the top half of the image indicates that this is a channel created by liquid flow. In this case the location and other surface features visible in the image indicate that lava flow rather than water created the channel. The more linear depression at the bottom left side of the image is probably a tectonic feature called a graben and was formed by movement along fault lines.
