Verde Vallis

The major Martian dust storm of 2007 filled the sky with dust and produced conditions that prevented the THEMIS VIS camera from being able to image the surface. With no new images being acquired, we've dug into the archive to highlight some interesting areas on Mars. The this week's topic is medium sized channels. Verde Vallis has a relaitively uniform width, but erosion of the walls has reduced the channel depth and makes the valley indistinct from its surroundings in some areas.
