Rain water run-off channel at Opportunity, Sol 103?

Do you think this could be a rain water run off channel?

I don't. But it sure looks like one. Could the wind do something like that?

I dunno, but why are those flat stones in the foreground so blue?

The obliquity of Mars is believed to have changed periodically on a
relatively short timescale (millions of years). Snow pack layering could
have melted, creating such channels/gullies.

It could be a water drainage channel -- we know that there used to be
standing water here. It also could be the result of aeolian weathering
of a surface that has varying compositions. In the latter case, the
channeling would be controlled not by the erosive force but by the
structure of the materials being eroded.

Is that color correct? What are the the blue pebbles?

No. You can find out more about how Daniel Crotty did the colour at
http://www.lyle.org/~markoff/ . He tries to explain why the hematite
gray blueberries appear blue. Something about:

"The image shown in the galleries above are no longer adjusted for
brightness differences between filter frames. It was vaguely factual
guesswork on my part, and often distorted the colors beyond reason.
The gallery images have all gone through identical treatment and
overexpress the brightness of short-wavelength frames, thus adding
green and blue tints to all objects. No hand correction is done to
distort the images. This issue will be fully resolved when
calibrated-to-radiance images are released and will be used here as
soon as they are available. "

Getting back to the rain channel picture. Why do you think all the
spherules have washed down to the bottom half of the picture?

It actually looks like water flooded and flowed down from the top and
washed all the spherules to the bottom half of the picture. Complete
with a rain or melt water channel. Maybe we ought to have our own
press conference announcing we too discovered water on Mars. I could
say what wake up music I listened to -- Kentucky Avenue by Tom Waits.

Round things are easy to push.

Here's one that may be a little closer.

Hey, hey, hey, check out this picture. Even more washed and flooded
over terrain.

It looked like there was a big rain there just two weeks, 14 sols,
ago. Or could you do that with ice and permafrost.
