The most comonly accepted explanation about these "liquid like" dark streaks is that they are dust avalanches. The process is as follows: every day a thin dust descends on mars ground (which was carried in the atmosphere by dust devils and large storms). This dust is light colored, a bit reddish. It accumulates on slopes too, but when it reaches beyond the equilibrium point, an avalanche occurs. This avalanche may be very thin, about a some millimetre dust layers. But when it flows, it left the darker terrain under to appear, creating these black streaks which strangely look wet, but are not. It is in the frame of this explanation that I commented above.

Perhaps, but not all scientists are convinced that they are dust avalanches:

Independent researcher Efrain Palermo had also published a good paper and compiled an excellent "stain map"; he presented his findings, along with Jill England, to the National Space Society in 2002 and the Mars Society Convention in 2001:

And no, they are not affiliated with Hoagland / TEM, before anybody asks...

I might have some other references also, but I need to find them again. There has been just as much debate about these features as the other gullies.

And by "not affiliated with" you of course mean a regular collaborator, having even appeared on stage with him at one of Hoagland's seminars: http://palermoproject.com/Mars_Anomalies/H...New_Mexico.html

That said, Efrain's work isn't the usual garbage that comes out of the anomalists group. He's capable of doing reasonably competent research for an amateur astronomer.
