I donīt think this is part of a crater wall. Note how flat-topped and steep-sided it is, quite unlike the variously degraded craters around this feature. My bet is that these are
esker.

There seems to be a lot of ice-related geology in this area. Those lobes coming down from the mountain in the center of the scene look like ice sheets with crevasses and flow lines.

HiRISE but CTX!

You're right. Forgot to mention that. There is no "The power of CTX" thread yet...

I checked HiWish and there is no HiRISE image over the feature. I won't preempt your find; you should go to HiWISH and ask for a higher resolution view!

You can go right ahead if you (Hi)wish. smile.gif But I don't think a higher resolution image would help in this case. The HiBlog warns:

First, make sure you justify the image in terms of small-scale features that might be seen, things like boulders or thin layers or dunes, not giant volcanoes or channels. We need to know how HiRISE’s meter-scale resolution is necessary, especially if there are existing MOC, CTX, HSRC or other images of the area.

I saw this strange feature. What is this?


Interesting. let's see how this thing might look like from the ground smile.gif
here is my attempt at rendering a few 3D views of the formation, obtained from the single-image SFS DEM algorithm (described in more detail in the other thread)

Nice work Nirgal. Looks very flat. Judging by the shadows I thought it had more relief.

Slightly different topic: Has anyone else had trouble with the HiRise site last couple of days? The Layout is all messed-up in my browser. I can't see the links to the IAS-viewer images anymore.

This is very strange. I can see those links again in Firefox, but in IE8 they are still broken. Does anybody know what could be causing this? blink.gif

Fresh looking crater (crater-pair?) about 9.5km south of Oppy's present position (also from ESP_016644_1780).

What part of the route is this? Everything's beginning to blur together for me, it's been so long and so far...

Thanks.
That was so long ago, it's hard to believe so much time has passed since we left Victoria, but it has.

Today's batch of new releases includes an image of Spirit's landing site, taken Feb 15th, on which Spirit herself can clearly be seen. Here's a colourised crop...
