Back to our regularly scheduled programming - a circular view of the position after the sol 3737 drive - north up the tracks.

Crumpler's post says the 3737 site (after the northwards drive) was a "Brief stop... to look at contact with plains". I suppose they thought that spot to the north was the best place to do that.

He also explains the eastwards drive on 3719: "it dropped down several meters to a saddle in the rim with a quick look back, just in case there was a view of the geologic section here."

The Sol-3719 4x1 mosaic looking back at Broken Hills. There is a data dropout in one image, but I couldn't hold this back any longer. I might update it when that image comes down. The rover is roughly the size based on the wheel tracks. smile.gif

Very nice - here is a circular version of it showing the tracks.

I initially took a look at this L2, 5, 7 false colour, assuming that it provided a cross section of the laminations beneath the apparent desiccation cracking. The laminations are evident and establish the original horizontal orientation of the sample, but what has got my attention is the apparent changes in composition delineated by what should have been vertical desiccation cracks. I'm not sure what to make of it. Dewatering pipe effect?

The sol 3744 drive starts the climb of Cape tribulation. Time for a new thread.

What is this cross-like feature seen in Sol 3720 Microscopic Imager image? http://mars.jpl.nasa.gov/mer/gallery/all/1...KP2955M2M1.HTML

The Opportunity Update page mentions APXS being used on that night, perhaps they placed it on the surface prior to taking this image?

Yep, that's an imprint of a screw head on the apxs plate.

APXS itself was imaged recently as well on sol 3795

So, I look at the picture, I look at the image of the APXS and I can't align it with the image.
Why have I not seen the 'cross' image previously.

Why is it that every time Opportunity or MSL post home an image that contains data that does not fit
the accepted Mars norm' its a case of move on people, nothing to see here.

The APXS design has screw heads at 60 degree angles (hexagon). The anomaly referred to by 'wildespace' has imprints
at 90 degree angles.

Yeah, it is obviously an imprint made by the APXS?

By hexagon, are you referring to the actual apxs sensor, which is inside the outer ring and never touches the surface? Check out this image for a better view.

The imprint in the Sol 3720 MI image is of one of the Philips head screws in the ring/plate surrounding the sensor head. That's the only part that should ever touch the surface.

Maybe this set of images, including the one fredk linked, will help situate things.
(Note: the bottom right image is of the bottom screw in the color image, rotated to match the orientation of the imprint.)
