It looks to me like there's a source above one of the streaks, circled:
Some material has accumulated in a precarious spot on the rock face and some of it has collapsed away and spilled lower down to form the streak. Similar sources for the other streaks could easily be hidden by the rocks. |

An isolated occurrence of newberries? Remnant of Matijevic formation? http://qt.exploratorium.edu/mars/opportuni...PRP2372L2M1.JPG |

Another A.J.S Rayl update provides a good start to Opportunity's new year in Marathon Valley.

Amazing that the RAT is still sharp all these years after landing (though I do recall that the Meridiani rocks are much softer than those Spirit encountered, so perhaps not)!

Patch of dark soil near us imaged on 4262:
http://qt.exploratorium.edu/mars/opportuni...5M1.JPG?sol4262 I think it was material dropped from a wheel. You can see it as far back as 4223 where you can see tracks near by (at 11:00 from the dark streak): http://qt.exploratorium.edu/mars/opportuni...0M1.JPG?sol4223 At the 4200-4205 location we were sitting with our RF wheel very close to the dark streak: http://qt.exploratorium.edu/mars/opportuni...0M1.JPG?sol4201 I'm guessing that's the wheel it came from. |

MI closeups of the dropped soil tosol:
http://qt.exploratorium.edu/mars/opportuni...2M1.JPG?sol4263 I forgot to add: To prove this was dumped by a wheel we should have images of that area before we first drove there on 4200. I looked but couldn't find any... |
