Reminds me, ever so slightly, of Anatolia back up in the Eagle-Endurance days.

I'm wondering if we will see different kinds of bedrock once back on flat terrain...

Speaking of feature names, "Surveyor" (crater?) is on the list of images planned for today, sol 1782. My guess: it's the tiny crater almost S of the current position which will be imaged on a "mid-drive" mosaic.

That would be a good guess. The answer is in about 10 hours.

I wonder if the three craters formed at the same time from meteor that broke into several pieces? They look similarly eroded.

Now this is exciting. Looks like there was a pretty long drive to the south and west on sol 1782. And although I'm no judge of these things, it looks like the drifts are thinning out quite a bit!

Here's the Navcam mosaic (so far), I left it in full equirectangular facing south in case anyone wants to reprocess it.

I think your right Mike. Looks like about 110m SSW

If you believe my ripple size mapping then we're through the roughest seas.

My impression is that we already crossed the worst of it. Still rough but less on each driving sol.

Do you mean the worst of the whole drive, or merely of this segment?

Thanks for the location update on your ripple map, James. Looking at that map and Tesheiner's route map, I can see two options now. First, continue farther south, until we reach the smoother, blue region on the ripple map, then head east. The second option is to head east around now, following the patches of exposed bedrock, even though the ripples are somewhat higher here. I'll guess that they'll drive a few hundred metres farther south, then head east along the southernmost reaches of the current stretch of exposed bedrock.

On another topic, has anyone else noticed the small raised ridges in the bedrock at the sol 1782 location:

Presumably old fissures that filled with a harder material. Does anyone remember seeing features like this before?

There were features like that at in Endurance, IIRC. What I found interesting was the way the feature seems to be split, possibly implying some sequence of events.

Also the feature's placement way out here in the middle of nowhere might be interesting, although I don't know.

Worst of the whole drive - depending on the route taken.

Several kilometers of these slightly smaller ripples before heading out onto the 'parking lot' (like the terrain around Eagle/Endurance) a couple of km's before 'mini-Endurance'.

Here is the whole route with a green dot for our approximate location.

A long way to go...

If, since their formation, at the same time or different times, the craters were filled in and covered and are just now being uncovered, the similar degree of uncovering would be no indication that they were formed at the same time.
