For those interested in current Mars conditions here's the clearest soil avalanche yet to have taken place during a rover mission, that is, between two images. The third image shows a further minor change in the breakaway line at the top of the slide:

This again reminds me of the gravity of the
event,,,,,,one third approx,,Earth Gravity.

At this gravity we must look at gas differently.Or the lack of.Soils would tend
to be joined much looser than on Earth.
Density of mass can be anything between areo-gel or granite.On Earth.

Not so on Mars.Mars gravity can never produce granite-like rocks.Common sense only.No other references or papers.
Volcanic? Possibly????

Kye,,what is the time-lapse on this?

JHD, The file names of the images include the sol numbers: 179, 192 and 232. I wish we could be sure that all the little soil disturbances on slopes that we've seen at Gale happened independently of the rovers presence. If this level of activity is normal, that is, without any rover vibration to trigger it, then Gale appears to have more movement than Meridiani or Gusev. I'm really looking forward to getting to bigger slopes and the bigger ripple-fields that lie ahead.

wind gradient,may be slightly different than Earth,,,but I would think rather close.(in principle)

So yes this trend should continue.

The wind will bring sharper quicker events
such as temperature and air pressure.Making
regolith reflect changes sooner.And with ascent we will be able to see further,,and more clearly.

My only fear is that to me,, the rover by no means meets the requirements of a mountain goat.
Scramble it will not,,,or perhaps it will.
Hope we don't have to find out.

Wind has scattered some of the drill rock dust.

New analysis suggests wind, not water, formed mound on Mars

Mount Sharp may be a huge disappointment for those of us hoping for signs of life.

Whenever one Mars scientists says it was formed by water there is always another that comes up with a way that it could of been formed by wind or ash or gravity ect. Not to say it could not of been wind or ash or ect that formed the mount or channels or Hematite or clay. I am just not to worried yet. Think Mount Sharp is going to be GRAND. Very Happy

Looks like there will be a visit to Shaler on the way to Mount Sharp, the cross bedding shouts out water origins so a bit of drilling here too. The study of these rocks should tell us how much, how deep and how fast the water flowed including which direction it came from.

Sol 0194 0226 0267 animation of erosion in Yellowknife Bay:

Quite a bit of erosion in just 10 weeks. Why are there not more dunes in Gale crater? Perhaps Mount Sharp is just one BIG dune?

How are these white patches related to one another?

Horton's #353, I think only the surfaces that have been broken and exposed are eroding; the intact surfaces appear to be unscathed

Sol 0272 after the move to position 60068:

The MSL ( Mars Science Lander? ) has moved! It last moved on sol 0166. It spent 106 sols ( longer than the Phoenix lander nominal mission of 90 sols ) in one spot.

Looks like this is the next science target.

More "berries"??

Oops.

The next target is the flat bumpy rock Cumberland - next to the rock in reply 358.

Hort; Thanks for the info.

Does anyone else think that these rocks look very much like the Oppy newberry rocks? If they do turn out to be chemically related it might be interesting to see if the original characterization of the "newberries" stands up to the likely increased data that Curi could provide on these rocks?

Very interesting!
