Are Those Spidery Black Things On Mars Dangerous? (Maybe)

You are 200 miles directly above the Martian surface — looking down. This image was taken by the Mars Reconnaissance Orbiter on Jan. 27, 2010. (The color was added later.) What do we see? Well, sand, mostly. As you scroll down, there's a ridge crossing through the image, then a plain, then dunes, but keep looking. You will notice, when you get to the dunes, there are little black flecks dotting the ridges, mostly on the sunny side, like sunbathing spiders sitting in rows. Can you see them?

@Joe Nation,

My thoughts exactly. Spiders trump the merest possibility of dirty ice any day.

@Joe Nation,

Thanks for the expandoview. I think theyre stuff we call "lag sands". Wind will sort **** out according to density. If you go to the beach and stand in a small wave channel you can see how black sands pile up in areas that are where the current suddenly drops and areas are she;ltered. I think its sorta like that except that its done with the wind here. We have that on earth. Look up "wind lag deposits of black (or Titanium) sands

HERES an example I found from South African Titanium fields. The black stripes are Ti sands

@farmerman,

Very cool, and of course I've seen those streaks of black sand on the lighter sands in many places on many beaches and never gave them a second thought.

PS. Looking at the bottom scribble, it appears to be Arabic writing on MARS. It says ALLAH
