I enlarged your image and here is what I got. The second image I brightened a bit to see<br /> more into the dark spots. <div class="Discussion_UserSignature"> Ron Bennett </div>

Here is another one. Lots of large root type systems on the cliffs?<br /><br />092-070904-0334-6-3d2-01-OphirChasma_hires <div class="Discussion_UserSignature"> Ron Bennett </div>

I haven't been keeping track of the debate on the berries and what they are but something occured to me that might be way off or might have already been discussed.<br /><br />Is it possible that they are simply a shower of molten rock thrown up by a meteor strike which have solidified into fairly regular little spheres as they they cool on their passage through the thin atmosphere?<br /><br />Please forgive me if this is too idiotic. <div class="Discussion_UserSignature"> <p><font size="2" color="#339966"> I wish I could remember<br /> But my selective memory<br /> Won't let me</font><font size="2" color="#99cc00"> </font><font size="3" color="#339966"><font size="2">- </font></font><font size="1" color="#339966">Mark Oliver Everett</font></p><p> </p> </div>

The bottom of Victoria looks like it has the same sand dune like features that Endurance has. <div class="Discussion_UserSignature"> <p> </p><p><em><font size="1" color="#000080">Don't let who you are keep you from becoming who you want to be!</font></em></p> </div>

<i>"...the berries.... simply a shower of molten rock thrown up by a meteor strike <br />which have solidified into fairly regular little spheres as they they cool...?" </i>-- Tom_Hobbes<br /><br />Back when the berries were first seen by Opportunity, this was one of the theories. <br />It was discarded when examination of the layered, berry-containing, rocks of Eagle crater showed that <br />the berries formed <b>within</b> the rocks rather than falling onto a surface which was then covered. <br />The loose berries are the result of their being released, by weathering, from the rock within <br />which they formed. <div class="Discussion_UserSignature"> </div>

<font color="yellow">formed within the rocks</font><br /><br />How could that be known. Is it possible that those were older berries from previous ejecta showers, covered over by dust storms, fresher impacts, heavier ejecta coverings etc? <div class="Discussion_UserSignature"> <p><font size="2" color="#339966"> I wish I could remember<br /> But my selective memory<br /> Won't let me</font><font size="2" color="#99cc00"> </font><font size="3" color="#339966"><font size="2">- </font></font><font size="1" color="#339966">Mark Oliver Everett</font></p><p> </p> </div>

Here's a timeline of press releases showing the evolution of the concretion theory: <br /><br />From the 2/9/04 press release: <br />"The spheres may have formed when molten rock was sprayed into the air by a volcano or a meteor impact. Or, they may be concretions, or accumulated material, formed by minerals coming out of solution as water diffused through rock, [Squyres] said." <br /><br />From the 3/2/04 press release: <br />"Round particles the size of BBs are embedded in the outcrop. From shape alone, these spherules might be formed from volcanic eruptions, from lofting of molten droplets by a meteor impact, or from accumulation of minerals coming out of solution inside a porous, water-soaked rock. Opportunity's observations that the spherules are not concentrated at particular layers in the outcrop weigh against a volcanic or impact origin, but do not completely rule out those origins." <br /><br />From the 3/18/04 press release images: <br />"The thin layers do not appear to deform around the blueberry, indicating that these geologic features are concretions and not impact spherules or ejected volcanic material called lapilli. Concretions are balls of minerals that form in pre-existing wet sediments." <br /><br />From the 3/18/04 press release: <br />"Scientists had previously deduced that the martian spherules are concretions that grew inside water-soaked deposits. Evidence such as interlocking spherules and random distribution within rocks weighs against alternate possibilities for their origin." <div class="Discussion_UserSignature"> </div>

We still don't know enough about the sperules, my conjecture when we first found them were that they look so much like Yellowstone geyser berries, even the color seemed to have matched that were so popular in the 40s. Unfortunately most of them were picked by invading tourist. <br /><br />They did find hematite present in them, other than that I haven't been following the latest updates on them. CentsworthII has just posted some more information on the latest findings.<br /><br />Here are some more images fresh off the presses.<br /> <div class="Discussion_UserSignature"> Ron Bennett </div>

<font color="yellow">The bottom of Victoria looks like it has the same sand dune like features that Endurance has.<font color="white"> <br /><br /><br />Yes it does. As allready been noted it looks deeper with sharp edges, the dunes looks the same <br />as Endurance but the rest may not be. Victory crater may give them a better recent view of <br />exposed sediment and rocks.<br /><br />2P147855086ESFL5M1</font></font> <div class="Discussion_UserSignature"> Ron Bennett </div>
