Barsoomer,
I like your hypothesis. I think that may also explain why the terrain is relatively smooth and free of the boulders and rocks that curiosity is imaging in Gale. It just looks like it was recently (geologically) wet.

BTW, Your last post did not show up for me until early this morning, a day and a half later...

New image of the shining hill from a closer vantage point.

Complex structure beneath the fabric of the hilltop.

Here is another nice view:

New image of the shining hill combining L456 filters. I think this is approximately how it would look under Earth lighting conditions.

Might be some stories in this boulders. I wonder if there is a way for the rover to get to the top of this hill?

Barsoomer,
Also wonder if under the hill is a small remnant of a former ice shield similar to the one that may have been at Lyot Crater that you linked to in the other thread.

John, those are good suggestions. Unfortunately Oppy is having a mechanical; problem at the moment with the left front steering actuator, so it may not be going anywhere for a while.

On UMSF it is being reported that the left front wheel has been successfully straightened. So Oppy may be hitting the road again soon. Three cheers for the engineering team!

Bright stone stands out from surroundings. (Bottom towards right.) Shadow from stone not seen.

Could it be Ice? Out in the open? I noticed this last night. I wonder if the mission team will comment on it.
Here is an interesting nary ridge, or maybe beachhead:

John, thanks for the comment. The object seems to be standing up but not casting a shadow. The face we see seems very flat and perhaps it is very thin if that explains the lack of an apparent shadow. Could this be a mica flake?

Mica is a possibility but there is no way to be sure. It makes me think of the bright spots on Ceres. In 3D It looks like the object is upright but that may be an illusion. I searched the navigation images but have not been able to find our bright spot in any of them. The bright spot seems to have small stubs of filaments on the top and lower right side, but the image is too far away to trust the details. I have found a number of other bright reflective rock surfaces but nothing as bright as the object in question. In the upper left there is a bright reflection off of a relatively flat surface area:

Could it be a salt deposit such as what the Ceres bright spots turned out to be?

The other rock with the flat reflective surface can be seen again in the right edge of this image just above the middle:

Opportunity Status

MER Press Release

The MER scientists are puzzled because the land to the west slopes away from the crater. They assume the water that spilled into the gully came from the west. More about this in A.J.Rayl report:

MER Monthly Report from the Planetary Society.

But what if the water came from the south and some went west while some spilled into the crater? The source path of the water might even have collapsed into the crater.

Weird effect of the light shining through the wheel spokes.

Nice find! I'm downloading this one.

We are now in Perseverance, the valley of the gully. Note the bright region in front of Oppy, even though the Sun is behind the rover.

Unusual rock behind the pancam calibration target.

This is starting to get interesting. The dark stuff, perhaps reminiscent of beached seaweed, might be worth investigating.
