Actually the view is Mt. Shields - the wheels are on Logan's Run. Not sure about accessibility but these are nicely differentiated outcrop layers.

Yes... the new USGS blog gives us the details. I'm hoping for one of Fred Calef's nice maps annotated with placenames to give me some more certainty about other names.

Excellent, thanks! Just using that I have been able to fix and add to my map, so there is an updated route map today.

With reference to post #626, I noticed that the right 55% or so of the image is predominantly sand and the left mostly stoney.
I kind of assumed that it was to do with the prominance of the rocky outcrops catching wind blown grains, and therefore defining some sort of boundary, would this be correct?

..you probably mean
post#256? if so id assume the opposite cause, sand dunes likely indicating the prevailing wind patterns with the leeward side of the ridge where the sand collects atop the otherwise similar stony terrain sourced from the windy side where it is blown relatively quickly off of over to the leeward side. in any case the question remains how long has it taken for this to accumulate?

Possible, but there are several depositional environments that can have inclined bedding. This is just an isolated small outcrop. I'd probably want to see more of the package (e.g., a complete sandwich including horizontal topset beds on top and bottomset beds underneath) before arriving at such a hypothesis.

The way things are turning out, I think it would be more likely to see Opportunity in Gusev Crater.... where it could nudge Spirit back into life, and then they can travel to Eagle Crater together.

Those layers "look" extremely delicate.
Amateur Question: Would the arm or turret ever be used to try and break some of these rock layers (maybe by preloading the drill against it, for example)? Would there be any science gained from such an action (maybe to see the inside of a rock or measure shear strength)?
Just wondering, thanks.
Phil Stooke
May 2 2015, 03:04 PM
Absolutely not the arm! It's full of delicate equipment. But the wheels sometimes break rocks as they drive over them (Curiosity in Yellowknife Bay at Snake, for instance, or Opportunity at Pinnacle Island) and sometimes it's even done deliberately to create a fresh surface for analysis.

It must be Charity, because according to the USGS blog Albert will be the site of DRT brushing later... and they would never brush that flimsy thing.

A close-up on the hills and canyons of Mt Sharp. I'm looking forward to see Curiosity driving in this region!
That valley up the middle in the distance looks so similar to the Devils Corkscrew coming up out of the Grand Canyon! Awesome.
Question on Colors: Ive noticed several of the images were the sky has blue-ish tones, but recently the sky is very orange, is it just different angles/time of day, or is the color processing different? It doesnt seem like a dust storm because you can see so far and details on the hills that are 10-20 miles away, maybe upper atmosphere dust?

Martian sky color has be much discussed here in dozens if not hundreds of threads and you can find out a lot by searching and reading. Orange is usual--close to what we would see if there--blue shows up in color stretched images and some sunsets. Skies are only blue on Mars if you are in a spacecraft above a high percentage of the atmosphere...

I believe that's Navajo sandstone, and it erodes into domes in a number of places, like the San Rafael Swell and Capitol Reef.
My own photo looking off the swell. Always think of that when I see Mt. Sharp.

As fragile as the laminae look from a distance, they seem to be much more abrasion resistant than the soft rock at Pahrump:
No trace of a scratch from the DRT.
