# What is this strange feature on Mars in Valles Marineris

While I was browsing Mars on Google Earth, I stumbled upon an interesting feature on one of the slopes of Valles Marineris. The feature seems unique in the sense that I couldn't find any similar element on the valley.

It made me think of sand that just fell from the clifftop or the veins of water that have already been observed on Mars (such as http://www.wired.com/2011/03/happy-birthday-mro/#slideid-591036). But it doesn't seems to match completely with this explanation.

Does any of you have seen this before from current Mars research or from similar phenomenon on Earth?

• There is a lot of interpolation going on. So it may not mean anything. For example, in your second picture, in some regions the top of the hill connects to the next layer in a very discontinuous fashion. Which seems to indicate an artifact of the interpolation. While these images come from the HiRISE camera it does not guarantee that what is presented by the google mars engine is anything like the 0.3 m resolution pictures we can obtain. space.stackexchange.com/questions/1140/… Jan 28 '15 at 7:52

• It's really hurting my brain that these two images are from opposite angles. I can't figure out the shadows in the first one. Jan 30 '15 at 4:48
