Thanks jules! I put them as "other" as you said. This image had no craters big enough to mark, but so many features that I almost wanted to just mark the whole thing as an interesting feature...  ;D
Lots of lines and boulders, and look at the two big pyramid shaped ones, one in the upper left quadrant, and the other in the lower center. And just NW of the upper "pyramid" is some form of line that looks like a "fault line" or something, or maybe the edge of a lava flow.

That is a very interesting site, Peek!  Lots of cracks, probably cooling cracks.  When I run across a pictures like that, I just mark the WHOLE picture as "Other", and send it on!  Welcome to the Moon (forum).  I'm Thornius in Nashville, Tennessee, U.S.A.

There is a fallen Obelisk on the lower left, but I can't QUITE make out the hieroglyphics on it.

I love this bouldery area.  The crater just above and to the left of them has collected a few.

That means that whatever event deposited the boulders is younger than the crater itself......INTERESTING!!!

That... had not occurred to me, but now that you mention it, yes.  I hadn't even gotten around to thinking about what order things happen in on the Moon.  Thanks.  That adds another dimension of observation for me.

I just love these "patties". I wonder how long it took them to degrade to level, or whether they were filled from below, so to speak, before all those boulders arrived to decorate them so gracefully?

Hey Weezerd,

Great image!

I don't think those craters are flat, though. After all, you can still see the right side has way more sun and the left side has shade, just like the smaller craters in this area. So, while they are very much degraded, they aren't quite flattened yet ;)

Also, to me, it looks like the boulders come from the top of the crater rim, since that is where they are most plentiful, and some have moved down slope closer to the crater centre/bottom.

It's from the Early Dynastic Period  ;D

Humm! At normal magnification, there appeared to be a flagstand or something just hiding behind the large boulder in the top left corner. But, increasing the mag a little and now it looks, to me, just like a smaller boulder that hasn't hid or camouflaged itself sufficiently behind the big bright boy!

Now... it was my understanding when I joined this luau that there would BE no math...



That's the first one that's ever come up for me that wasn't a pretty clear cut choice.  I thought the one on the right was a slam dunk at first, but I think a lot of little pits from the initial strike are masquerading as other boulders in that one.   I still think it's the one on the right, but the one on the left is deceptive.  There are a lot of boulders there.

Oh, and I really like the striped safety cone near the top left of the right hand picture.  Man, road construction crews even have traffic gummed up on the Moon.

I have a question about that.  I would have marked that object as interesting but in Boulder Wars there doesn't seem to be an option for that.  Nor does there seem to be any way to figure out where you're looking or to alert others that something important might be there.  Is this something they plan to fix or do we just sigh and move on?  Another question: What constitutes a boulder?  If we see what looks like a vast field of crushed rock head to head with an area with two or three large boulders, which would we pick?

Hi DJ_59

I would have selected the right-hand image as well. I don't think we are meant to agonise over the choice of one or the other, just select the one that you think has the most and move on.

If you want to find out more about a particular image go to My Moon Zoo immediately after clicking on the "Most Boulders" button and look in the Recent list on the right-hand side, the two images from boulder wars should be at the top of the list.
