Barsoomer; If you are referring to those rocks in the R center of the image, I believe they represent Meridiani beds that are tilted slightly upward by the impact.
These thin ,alternating beds have been exposed to erosion that created the conical,rock shape and which be due to the relative degree of harness of this broken exposed surface compared to the flat surface that could have a slight crust.

Further back on the slope is a block of similar rock that is tilted into the crater and eroded so that the beds look like bands.

Barsoomer, re your reply 60, you ask, "Why is the part just outside the crater planed down, whereas the part inside the rim seems pristine?" I think that both the "planed down" rim surface and the much rougher wall surface have been heavily eroded. If we knew HOW either one were eroded this would be a big improvement on current knowledge and probably explain why they are different. Here are some similarly rounded shapes eroded into bedrock in Duck Bay (center left):

It is interesting to me that these rounded shapes at Santa Maria, Victoria and other craters seem to generally be oriented in the same way relative to the crater, that is with the main axis of the "cone" or "cylinder" running up and down the wall.

Interesting image, Kye. Outside the rim, beyond the planed-down part, there is another even rougher irregularly eroded layer with a dark coloration.

4. What EDRs did we request?

Expected EDRs by sequence number and image type:

sol 2569 ( Apr 16, 2011 ) L257 2x0.5 Endeavour pan taken just before the sol 2569 move:

The sol 2569 drive was about 104 meters as measured from the sol 2569 traverse map.

No drive yesterday or today ( sol 2570 or 2571 ).

Still cleaning out flash memory?

Beautiful panorama Horton. The sol 2569 traverse map that you linked in 66 shows a texture that Oppy has not yet encountered. The extreme south east corner of the map shows something like a tiling pattern with elongated polygons. Maybe Oppy will cross some of this type of ground ahead.

I can no longer look ahead at Hirise resolution except on these traverse maps. Does anyone know of easy access to a Hirise image that covers the area ahead?

Wow, re:66 is truely spectacular, the most inspiring image you have posted in some time. OF course, they are all awesome, but this one is really jaw dropping.


Just imagine what we will find in those distant hills, that are coming closer day by day. What we find in the future is truely unknown, perhaps we finally will find evidence of life on Mars, past or present.

Nice image in your 66...so much so I downloaded and placed them into stereo image maker and I am sure there is a fog surrounding that large hill, and perhaps the whole crater is filled with fog too!!!

Do you think you see the same thing in your image?

Kye,

Why no hirise?

How about google mars?

Psych, re your 70, Thanks for your interest in my problem. I've been using this website to view a Hirise image centered on Victoria Crater, but now Oppy has rolled off the edge of it:

http://marsoweb.nas.nasa.gov/HiRISE/hirise_images/

I haven't found such a good source, high-resolution and a good interface, for the area between Santa Maria and Endeavour, but I haven't put much effort into looking. Have you found something this good? I'll try Google Mars again. Its been a while.

Posted #66 on Twitter, this has to be shared, we cannot keep such amazing work just to ourselves. Wonderful image!

Kye,

I thought you might be having machine issues.
I'm using Google mars with HiRise imagery overlay created by users from that other web site (UMSF) and hosted online @ http://planetary.s3.amazonaws.com/gmars_maps/Opportunity_base_maps.kml.

The drive on sol 2572 ( Apr 19, 2011 ) advanced the drive index from B4IT to B4X2 during a 2 1/2 hour drive, so my best guess is the drive was around 100 meters to the SE and the sol 2572 position is about 30 meters east of a shallow 7 meter crater.

None of the after drive images have yet been posted - so no drive today. Today's ( sol 2573 ) plan is a 360 degree L1 panorama.

Kevin, I wondered why reply 66 image already had 200 views. FYI, the image still has a lot of missing data and I constructed the image with interpolated data. I don't think it will look much different once all the data is downloaded - maybe a tad sharper.

Does anyone know exactly where Cape York is in the image? I have a thought, but I haven't yet bothered to pin it down. Maybe next month the position of the cape will be more obvious?

Cape York, I was under the impression we may not see it until we sit on it...as what appears from orbit as a hill, may actually be a ledge.

with a link to the L2 4x1 pan in the next drive direction.

Oops. Cape York is to the left of the reply 66 image. It should be about 8.5 degrees to the right of the far wall crater in the linked sol 2572 pancam panorama. I don't see anything there - but the pancam image used was incomplete.

I am quite new to Twitter so not a lot of followers but also put it on Facebook as a lot of my friends like being pointed in the right direction for Astro stuff, you bring pleasure to the World Hort.

I also follow the #Marsroverdriver on Twitter plus several other Space Projects and Agencies, really useful updates and people sharing things such as shots from the ISS almost in real time.

It is amzing what the average Joe has access to, we live in an amazing age, when I was a kid a few black and white shots of Space would blow my mind now it is just simply overwhelming and awe inspiring!

I'm guessing Cape York to be just left of or on a line through the left edge of the double crater ahead to the horizon.

Psych, re your 73, Thanks, That Google Mars material works pretty well to see the route to Cape York. Somehow it seems a little short of full Hirise resolution, and I wish there were wider area coverage. It would be better for me if this excellent site would just add more full Hirise images:
