    What's this? A volcano?

    Looks like it has been smashed from the inside!

    The root like structures must be feeding the red gas deposits.

    when you look at this and other marks you wonder if mars had a catastrophic failure of its core which lead to loss of magnetic shield,

    it looks like river beds that are going up a mountin that's why it gets thicker when they join

    Are those tree like #roots, #veins under the surface? They seem to cast #shadows; or is it an optical illusion? river #tributaries?

    Looks like a volcano with lava flows to me.

    is it poor humid soil's erosion phenomena ? if yes it must be due to continued contraction and expansion of martian surface at night and day

    the martian soil surface contracts at frigid night but expands at warm day and this must have caused such streaks on land.

    thermal contractions usually don't have a central point, because all material expands from every else.

    Looks like a dust eruption in progress! What is the size scale? What time of year? How long does the orbiter take to collect such an image?

  • jshoe by jshoe

    RE"Eruption" Is the orbiter typically directly overhead or slightly off? Dust in "midair" explains feathery structures & diffuse edges

  • michaelaye by michaelaye scientist

    it's soo ever slightly off, that we still wouldn't see anything from the side, considering the 300 km distance.

    what signature makes u believe it's in progress,maybe i'm missing something?To me it just looks like a quite big fan eruption blown away.

    What's current theory for change of surface color: reduction of Fe3+ or local removal of same? Is there surface scouring near spider legs?

    Posted

  • jshoe by jshoe

    I forget that this an unusually perfect canvas for collecting and holding piles of dirt where they land! That changes things. See next!

    Posted

  • jshoe by jshoe

    Subtle changes of color near the blowhole concern me now. I was unable to see these earlier. Are any of the colors "real"?

    Posted

  • jshoe by jshoe

    This image still amazes me, especially the feather-like structures on top right although I can see possible "dust from cracks" for some

    several frost fans overlap on a spider with thin legs; above them there seems to exist shallower spiders(left there last Mars year?) #frostreview
