In a lot of MER images from Opportunity and Spirit, there are areas where there are no small stones. These could be between rocks or in small channels
in the ground. There are small stones all around the area concerned but for some reason, they are not in these cleared areas. I can understand how
these may be places where there are rocks under the surface where the soil has sunk into these groves between rocks. That has been an explanation
offered by others to similar queries.
However, there are too many of these areas for them all to be explained away as this. Some look like there has been a fluid flowing which has moved
the small stones to the edge - rather like a stream or river does. Some cleared areas do not seem to be linked to anything in particular and appear
around a rock. ALL the way around, not just on the windy side. If it was caused by the wind, you would expect the stones to have been moved to the
side opposite the windward side.
As an example, take a look at this front hazcam image taken
by Opportunity at site C7
On the right in the corner, you will see a rock cleared on 3 sides and in front of the rover you will see a few
channels between rocks where there are no small stones. Both these areas are strange because there does not appear to be any way the liquid (if it was
caused by that) could reach these places.
I cannot post images to the upload area at the moment, not sure why, otherwise I would show an image in the thread.
In this image
of the same bottom right hand corner rock
area, there is also a grooved cleared area to the left of the rovers solar panel and to the right of that same area cleared around the
