Here's a new sol 1843 rock with some anomalous looking objects in a hollow on its surface.

Image magified X1.5., sharpened, auto WB and colour enhanced.

Anyone can guess what they are?

Looks like Curi's wheels broke some rocks with colourful interiors and also initiated a largish debris flow around here.

Sol 1845. Auto WB and colour enhanced in gimp. Some of the breaks might be interesting to some.

Domal Stromatolite?

Winston,
#282- Don't really see much of a hollow but it looks like rock chips on top.
#283- we have seen this before where rocks have been shipped and broken and the insides have the gray color. We have also seen the even sub-surface sand has a different color. So maybe there is something about surface conditions that make so much of the landscape appear as the same color.
#284- You could be right!

John;

#282; I think you are probably right but I would love to see a close up MAHLI of area. Of course that isn't likely.

#283; Just an image to record another instance of Curi wheels breaking rocks; debris flow as result of Curi weight / breakage; rocks having what appears to be anomalously coloured interiors and sometimes largish holes, etc.

Thanks for looking at and commenting on the images.

A new example of a "fresh" crater from sol 1866.

Image processed in gimp from a stitch made in ICE.

some terraces from sol 1868 that look different to any I've seen before.

Another look at a strange rock from sol 1041.

Very nice, Winston.

If I were a believer in ancient Mars civilizations, I might wonder if this was some kind of Rosetta Stone!

Thanks!

Here's a new rock of burpled colours from Curi sol 1879.

Opinion may be shifting away from the RSLs being primarily water. But if that is the case, then it should lessen the Planetary Protection restriction on visiting them. Their behavior is still strange and worthy of exploration. It is known that an RSL is within reach of Curi.

Off topic, but I couldn't resist mentioning

the interstellar object that is currently passing through our Solar System. Unfortunately, they missed the opportunity to name it "Rama" (after the object in the novel "Rendevous with Rama" by Arthur C. Clarke).

Barsoomer;

Re. your reply 393. My reading of the article
[link]
is that much smaller volumes of water would be needed for the RSL's than formerly thought, not that the RSL's and other mass wastings occur in the total absence of water. Thus it is still possible from their findings that there may be enough water in certain environments for the invocation of the presence and causative activity of putative xerophytic microbes at some stage of the mass wasting process.

The new research therefore puts the question of current microbial presence on mars in a framework that is in closer accord with observations by CURI.

Martian microbes may not need huge volumes of water for a minimal existence.

The Planetary Protection protocols should still stay!

Here's a sol 1754 rock that I seem to have missed earlier. Its an excellent example of a rock surface showing many of the elements that I think might be associated with past or present life; i.e. veins, mudstone, concretions, pinnacles, etc.

The various colours of the elements are particularly striking.

There's been some discussion the last couple days about these odd formations that Curiosity is looking at right now. The objects appear "twisted and broken" and darker than the rocks they are on. I also noticed a "line" of little similar-looking "blotches" running along the surface of the rock, just to the right of the largest twisted object, best seen in first image below (sol 1923). Also an interesting Facebook post from Leonard David:
