The four stones in the one image look all the world like stone coping or section of decorative trim

Paul....I found a hollow bubble type rock on undisturbed sagebrush ground in Montana 50 years ago. It was about 3x4 inches by 5/8 inch thick. Looked like amber and was translucent and pitted as if by rain. Reminded me of a ravioli. There was powder inside. I'd wet it and reverse illuminate it with a flashlight and watch the powder move around. One day my curiosity got the better of me and I cracked it open. There was a very fine ochre colored powder inside. As my entire collection was stolen years ago by an unscrupulous rock dealer (had it on loan to him for display), I no longer have it. I'm going back to Montana soon, agate hunting, but I'll never find another rock like that one.

Paul Scott Anderson, re your 358, Thanks, I missed that "bubble" too. (Also see Paul's 328.) The outside of the rim is so seamlessly joined to the surrounding rock that a post-erosion (post Gale exhumation) theory for it's origin is looking unlikely. Now I'm guessing that the "bubbles" originated in the time of sedimentary deposition. Perhaps something rounded was included that erodes faster than the rock but it's presence made the immediately surrounding rock slightly more resistant. A gas bubble comes to mind, but could it form anywhere but right at a paleo-surface where there would be little pressure opposing it's growth? How about an icy inclusion?

Just a sol 129 image, auto white balanced and levelled to keep my hand in.

Some interesting small pebbles, yes?

I forgot to mention the white mineral filling that resembles the Oppy gypsum but seeems to have some other stuff embedded in it.

Hey guys. Sorry I'm not in this particular forum as much as I should be. That may change. Smile

But here's a 218 image-deep mosaic I just put together. Took a lot of time and CPU power to say the least. Enjoy! It's a GigaPan.

Derp. I forgot to mention - the above GigaPan is of Sols 110 and 111 taken with the MastCam 100mm. The image is enormous.

Hi, were my last posts deleted? I offered a link to a panorama at the GigaPan site.

Thank impreprex!!

Ok, look at the left most area of the image. Looks to me like this was one of the last places that water rested because of how low it apears. Now if you look at the natural pier looking thing. Imagine a pier just like it sitting at a beach.. well it would have mussles, barnacles etc attached and growing on it. That is the way I picture that one developing over time. I wonder if the reason that they have not chosen to check that out is because of fear the rover would get stuck in the mud?

Another Mastcam from sol 110 - a bunch of the "bubbles" on this bedrock slab; they kind of look like barnacles.

You're welcome, guys. Smile It's my pleasure - I love doing it. And no one Gigapans anything, so I learned this all just to do it.
But I do mosaics like this all the time - sometimes 2 in a day, sometimes 2 in 2 days, but just keep checking at the GigaPan site. Clicking my screen name on the Gigapan site will show you all of my panos. And I tend to use thumbnails that I blow up to 1200x1200 because I'd rather see that mixed in than a black box or black boxes.
