I found some straight lines on an image - see image:

Is this from the image processing or is it real?

Sorry if this question is in the wrong thread. How do I classify the little white bits? They look like points of light, if anything.  :D

They're very evenly spaced and so straight I'd guess they were not natural features - co-ordinate grid maybe?

Difficult to know without a scale isn't it? Think I'd mark them as "interesting" bumps and humps for now - 'till we get our eye in.

Are we meant to mark large bouldery areas, if they are not in craters and if so do we just say 'other' interesting feature as I can't find a more suitable option.

I had an interesting boulder strewn area which I saved as a favourite but now can't see how to retrieve favourites  :(  Maybe it's not working yet in the beta?

I would agree - mark them as other/interesting. Things should become clearer when enough of us have classified and we get some feedback.

As far as I know favourites should save - though they won't be transferred over to live Moon Zoo. Haven't tried it yet - forgot!

This is an interesting boulder strewn area. The area looks symmetrical - if you draw a line down the centre of the area it has almost mirror symmetry.

Please any hint on those. I mean the dark shadows on the left of the crater. I didn't yet finish classifying the image, although I've added it to my favourites, but it probably appears only when finished (like galaxy also). So, apologize for the small images.
: Re: Lunar Features - channels, pits, domes, tracks
: jules April 07, 2010, 01:25:05 PM
I think they are just the shadows inside the crater tsiehta. Looks like the Moon was illuminated from the botton left for this one. Would that be right?
: Re: Lunar Features - channels, pits, domes, tracks
: tsiehta April 07, 2010, 01:30:37 PM
Thanks again jules. The first dark shadow looks much fuzzier than the second, so I thought it might show something unusual. And yes, illuminated from left.

http://moonzoo.s3.amazonaws.com/v8/slices/000009908.jpg (http://moonzoo.s3.amazonaws.com/v8/slices/000009908.jpg)

Is the area on the bottom left a boulder field or something else?

Is the bright white area on the right centre a crater?
: Re: Lunar Features - channels, pits, domes, tracks

Looks like a historic river, any advise please if it is a feature and if yes, which category. Thanks.

I'm hoping some of the experts will wander in and help us out soon but meanwhile I'd say yes to the boulder field and the bright area looks like a recent impact of some kind. Crater or lander? Probably a crater but the lighting isn't helping is it? There's a suspicious looking spacecraft type boulder top left too. :-\

Not sure what to make of this. I noticed five dots (boulders, small craters?) in a row.

I've taken a screen shot which I have attached - hope it shows up all right.

Hi Jules

I cropped the picture very small so it only shows the 5 dots. I could find the favourite and post that if it helps.
: Re: Lunar Features - channels, pits, domes, tracks
: Geoff April 09, 2010, 07:26:37 PM
This image shows five boulders or something in a row beneath the crater on the right-hand side in the centre.

Is this a crater chain or boulder track or something else (or nothing!)

I see them. Might be a crater chain I suppose - not really familiar with spotting them yet but it's a striking feature I think I would certainly mark it as something - crater chain or other.

I should think that 'most' of those are boulders... obviously very difficult to say - especially without any indication of picture scale.
: Re: Lunar Features - channels, pits, domes, tracks

YES!  We need some kind of scale on those pictures!  And a zoom tool too.
: Re: Lunar Features - channels, pits, domes, tracks

I think the pictures are zoomed as much as they can go (as Tommy mentioned in another thread).

I use a magnifying glass sometimes  :D

A scale rule below each image would be handy.

I have seen what looks EXACTLY like terrestrial river channels.  Coming out of highlands, twisting and turning, and as they enter the lowlands, fanning out to form a PERFECT river, "delta".

There's an elongate pit just left of centre I'm sure of it. Just looks too - well - elongated to me to be a standard crater.

Caro, one way to understand what you see is to locate the diection of sunlight. If you look at the crater to the lower left of the image you will notice the left side of the crater is in darkness. This means that the light is coming from the left, illuminating the right inner wall of the crater leaving the left wall in darkness. Looking at the large feature you will notice the shadow is on the other side suggesting this is a raised feature.

I think these may be cracks.

http://moonzoo.s3.amazonaws.com/v10/slices/000116691.jpg

Wow, cool. As a first guess, I'd say those look like cooling cracks in impact melt ponds.
: Re: Lunar Features - channels, pits, domes
: IreneAnt May 15, 2010, 05:21:11 AM
Check out the large, decidedly non-circular depression to the right of centre here. Illumination is from the left, so this is definitely a pit and not a hill.
Coordinates are
    Longitude: 312.475
    Latitude: 23.5332
The image is from the floor of Aristarchus crater, near the central peaks. Aristarchus is a fresh impact crater in Oceanus Procellarum.
(http://moonzoo.s3.amazonaws.com/v10/slices/000352601.jpg)
http://moonzoo.s3.amazonaws.com/v10/slices/000352601.jpg

Okay, I managed to track down the full image (http://wms.lroc.asu.edu/lroc/view_lroc/LRO-L-LROC-2-EDR-V1.0/M114267211LE) in the LROC WMS Browser. (I have posted instructions on how to do this in the LRO Resources (http://forum.moonzoo.org/index.php?topic=38.0) thread, if anyone is interested in trying it.) The orientation of this image at the LROC WMS Browser is flipped compared to what we're using at MoonZoo. So, here is a reoriented screen cap of the region. The yellow box shows the location of the original MoonZoo image.
(http://lh4.ggpht.com/_FU5zWVkaD14/S-4qwyU24SI/AAAAAAAAABg/bSKJki2T7_o/s800/M114267211L_clip.jpg)

As you can see, the original depression is just one of many linear depressions in this region. My guess is that these are all cooling fractures in the melt sheet on the floor of the crater. In any case, they seem to be related to the mound, which is, I think, part of the central peak complex. So maybe this mound contributed to the formation of the fractures, possibly by affecting the cooling gradient in the nearby melt?

In any case, neat stuff!

Hi tom128, there are a number of reasons for this change in shade. The reflectivity of the surface material is known as its albido; material that is highly reflective will have a higher albido than that which is not as reflective. In some situations certain areas may display high albido material due to geological activity such as impact effects, volcanic effects and even Moon quakes. It is, therefore, not uncommon to see two contrasting shades in adjacent regions. Also, the Moon's surface is not flat, the topography rises and falls with slopes, hills and mountains. When the Sun is low in the sky a slight slope downward can leave an area in shade. So, in this image it may be that the material on the right has a higher albido, or it may be a downward slope on the ground level to the left with a rise to that on the right.
All in my humble opinion, of course.  :)

Hey Hofi, 
They are probably cooling cracks, formed when something fluid (like lava or impact melt) solidified. As the top solidified, it contracted, causing it to crack.

This is a nice area to look at, but I'm unsure about something here.  Look at the attached image (I can't figure out how everyone's inserting images yet).  Left of center in the lower third of the image there's either a pit or a little outcropping that is throwing shadows.  Kind of W shaped.  Along the bottom of that there appears to be a crack.  Is that what it is, or is it just a shadow?

At the bottom of this image is something that looks very tall, judging by its shadow. Is it really something thin and tall, or is it just that the sun was at a very low angle relative to the terrain?

Lat = -9.64443°, Long = 15.6051°, Sun Angle = -88.31°

(I'm new at this, so I'm probably not understanding the Sun Angle. I'd think being close to a multiple of 90° would mean the sun was almost directly overhead, but I'm guessing that's not the case, given the long shadow?)

I always thought 0 degrees would mean the sun was overhead at the lunar equator. That would mean your image was taken at a very low angle so your boulder could be quite small and producing a long shadow.
We could do with a diagram! I'll see if I can find one.

That is a really cool image, Jules.
It's on the edge of Mare Serenitatis, and there are a lot rilles and ridges associated with the mare edge in that region. I wonder if this feature is related to those or something completely different (collapse lava tube? very low angle impact crater?).

Looks like a dark haloed crater to me, possibly volcanic in origin.

Is this the strip with Luna 20? I saw same-looking feature searching for the subject.

I don't know if it is the Luna 20 strip.  It's ID: AMZ1001i2b.  I found it because I was curious about something I saw doing Crater Survey.  If this is what a dark haloed crater looks like, this is definitely my first one of those.  It's quite amazing to look at.

I'd say that was a dark haloed crater illuminated from above.
Hopefully someone will jump on me if I am wrong!

Take a look at the lower right, there's a "net" of "wrinkles" running from that boulder pile on the lower middle all the way to to the right. They are pretty faded, so, you'll have to look closely.

Can anyone help me with those? To me, those look like rover tracks or something similar

Hi Caetano J - welcome to Moon Zoo. :)
I can't see anything track like myself and the location is not near any of the landing sites so the wrinkles are likely the kind of thing we see in lots of places. Fascinating area though in the Mare Frigoris - just lost half an hour taking a tour!  ;)

Indeed! I wonder how these were formed, I've never seen them arranged in a grid-like manner like that. Given the scale, they seem to be 1 to 1.5 meters wide, looks like miniature sinuous channels :D

Hey Geoff,
This area is in the highlands, right on the border of Mare Serenitatis and Mare Tranquilitatis, so it's close enough to have been partially flooded by lava. It looks like this hill may be the central peak of a partially flooded crater, or some other random high area in the highlands that didn't get completely flooded by the thin basalt deposits here.
Hope that helps...

Can a channel be raised?  I have been going by the idea it was like a canyon, ditch or whatever.  I love the texture of this image, by the way.  It almost looks like coral.  Whatever it is, it's huge.

Hi Thornius,

These aren't actually rilles. Rilles are linear depressions that are bounded on two sides by scarps (cliffs) that face each other. This area is actually on the slopes of one scarp of a linear rille (which, insidently, has a sinuous rille inside it).

That said, this is a really interesting texture. We see it a lot in LROC images and I, for one, am not sure exactly what it represents. My opinion is that you get this texture when something not quite solid (like cooling lava or melt) creeps down a slope. This is quite likely here, since we are in fact on the slope of a rille scarp. The problem is that you also see this texture in flat areas. So, it may be that it is formed when granular material (like lunar regolith) is shaken in a moonquake.  This definitely requires more study...

Hi ellmay and welcome to Moon Zoo.

Not sure what this is - I can find out more if you post the reference number and coordinates (they should be on the right underneath the Information label when you access the picture through My Moon Zoo).
: Re: Lunar Features - channels, cooling cracks, pits, domes

Could that be looking over the side from the top of a rille?  Or a collapsed lava tube?

It looks like a shadow to me. The sunlight is coming from the left.

I suspect this is the edge of a large crater but the master image doesn't show enough to be sure.

An interesting image anyway!

Hi meteoricide and welcome to Moon Zoo.

That's a great image. I think Deej also posted it a while ago but always worth another look.

Could you please remember to post the image identifier with the image so we can look at the source image - see how previous entries in the thread are posted.

There is a topic about how to post images directly without having to attach them: http://forum.moonzoo.org/index.php?topic=7.0 (http://forum.moonzoo.org/index.php?topic=7.0)

Hi Claymore and welcome to Moon Zoo.

Can you please post the reference number and coordinates with the image - they can be found in the "Recents" list on the My Moon Zoo page. If you see an image you want to post while you are in Boulder Wars, complete your analysis of the current pair of pictures and then click on My Moon Zoo on the left-hand side. This will show you the Moon map with different coloured pins and on the right-hand side a list headed "Recents". Click on the top link in the recents column and it will show you a thumbnail image of one of the two last pictures you had in Boulder Wars. If this isn't the one you want, click the second item in the list. When you see the thumbnail image you want, click on the "View more information" link within the thumbnail to see the full image and reference information.
: Re: Lunar Features - channels, cooling cracks, pits, domes
: claymore September 26, 2010, 10:21:19 AM
Maybe that works for you but when I go to my moon zoo while working in boulder wars the center of the screen is black with only favorites and recents as small links on the right hand side. The recents show up as photos with no other info. Clicking on the photos result in the jpegs only no further info is supplied.

So if nobody is interested in the photos with no other info guess I won't waste my time posting anymore.

Hi Claymore

Sorry the image stuff is not working properly for you.  Can you let me know which browser you're using and I can talk to the technical people about the problem.

When you click on one of the "Recents" links you should get something like this:

It also extends to the right - you can navigate around on the My Moon Zoo strip and follow these cracks.

This is close to Aristarchus crater which is an interesting area for unusual terrain.

Some sort of melt and flow.

Possible volcanice craters

Central crater with black spot. Also just below centre of bottom right quarter.
they also appear to have lave flows that flowed towards the left of the image.

Hi Astrospade

This is on the edge of Repsold crater which may have volcanic regions. Will need to explore a bit further.

I did an image of the week about this area, here: http://forum.moonzoo.org/index.php?topic=202.0 (http://forum.moonzoo.org/index.php?topic=202.0)

There are a number of mounds on the top left corner and along the bottom of the image and also a chain to the right of centre. these mounds seemto fall into lines, could they be volcanic in oragin.

This is on Aristarchus ejecta, which has been inundated with later lava flows. So, what you are seeing is probably ropey, weaving ejecta deposits covered by a thin veneer of lava. Neat stuff!!

To me, these just look like regular impact craters, one with another impact in the middle. But, it's hard to tell at the LROC thumbnail resolution. It may be worthwhile to download the full LROC image and see....

Thanks Irene,

Incredible how the lava coating makes for such interesting structures in that area.

Nice long series of cracks that is 6 photos wide. the last photos sure look like "something" was "flowing" at one time looks just like dried mud on earth.

Not sure what this coming out of the crater on the right side? ??? Or if that is even a crater?

Beautiful!! Cracks in a pond of impact melt that pooled on a terrace in Aristarcus impact crater.

By the way Claymore, your past 6 image posts are all from Aristarchus, showing predominantly impact melt from various parts of the crater (floor, walls, terraces). Some really amazing images there. Good work!

A bunch of "Pointed" mounds in this one. They look like they have two or three "Layers" to them. And the one in the center even has a "Felix the cat" shadow. :)

Here is a link to the  LROC  site talking about impact melt flow.  It may be a similar type of formation as it appears to be weaving around the craters but over a smaller area.  We know that impact ejecta carves out interesting designs, troughs, etc., in the regolith as well but the photo item in questions seems more sinuous but not large in scale like wrinkle ridges are described.  Very interesting!

Yes, I am probably missing a key ingredient to my impact flow comparison and that is a large crater impact  :)

It's hard to look at them and remember that it isn't water making those "flows". :)
I see some great images for 'Image of the Week' here, Claymore. Thanks for all the good work you're doing. I've spent a long time lost in the last few pages of this thread.  :)

Interesting impact melt flow in region above Bessarion W crater.

http://wms.lroc.asu.edu/lroc/view_lroc/LRO-L-LROC-2-EDR-V1.0/M117732304RE (http://wms.lroc.asu.edu/lroc/view_lroc/LRO-L-LROC-2-EDR-V1.0/M117732304RE) near bottom of photo strip.
Yes, this is very interesting. The thing that gets me is that it is a positive relief feature (pops up from the surface as opposed to popping into the surface). Also, it has two scarp faces, one on either side of the feature. If this was a negative relief feature, I would say it's a sinuous rille; we are in the middle of a large flat mare area and so would expect erosive volcanic features. If it only had one scarp, I would say it's a flow front, again because of the mare surroundings. If we were on the Earth, I would say this is an esker (http://www.uwsp.edu/geo/faculty/ritter/glossary/E_G/esker.html). But, none of these options work here.

I don't think this is a wrinkle ridge. It's far too small in scale and has some interesting braiding that does not suggest wrinkle ridge to me. I also don't think it is related to impact melt. There are no nearby craters that could have produced such melt, and it doesn't behave like impact melt. Impact melts are ejected or splashed out in a more or less single event. This looks like it was formed by long-term continuous flow.

The only thing I can come up with is that you have a rivulet of cooling lava, which thickens and starts to behave as a very viscous fluid. Think of candle wax. When the wax is near the candle wick, it is very hot and runny and can even carve out channels in pre-existing wax. But, when the wax runs further away from the wick, it cools and starts to solidify. The sides cool fastest, creating a levee of sorts that contains the hot flowing wax, allowing it to snake further along until it eventually hardens. I'm not a 100% sure this is what's going on here, but it is my best guess.

Here is an interesting area west of Spencer Jones k crater.  Lots of activity on this photo strip. http://wms.lroc.asu.edu/lroc/view_lroc/LRO-L-LROC-2-EDR-V1.0/M121118433LE (http://wms.lroc.asu.edu/lroc/view_lroc/LRO-L-LROC-2-EDR-V1.0/M121118433LE)

(http://i942.photobucket.com/albums/ad261/Tom128128/spencer-jones-kPNG.png)

Zoomed out it looks kind of like a rille. Notice item near the top right of the photo that looks like a wrinkle.

(http://i942.photobucket.com/albums/ad261/Tom128128/rille-M121118433L.png)

11.05,  166.64

Zooming in the wrinkle now looks more like a trench or scarp (I think).

(http://i942.photobucket.com/albums/ad261/Tom128128/channel.png)

Zooming out some, this formation may be located near the edge of a crater that may have been filled in later with lava. I marked possible rim of crater with white dashes.

(http://i942.photobucket.com/albums/ad261/Tom128128/crater-fillPNG.png)

Very interesting. The item is about a quarter way up the photo strip.  What do you think is going on?

Volcanic pits around Aristarchus.
Nice! 8)
Hey Jules,

You aren't likely to find volcanic pits in Aristarchus. That crater is far too young. Volcanism on the Moon is believed to have ended long before Aristarchus was formed. But, you never know....

Actually, I'm not exactly sure what Lead_Bullet was referring to in his original post, but I think I may see some cooling cracks in various impact melt ponds here.

Not sure what this is?  Looks like a linear feature running from top right towards bottom left but it passes through an old crater wall on the way!

I have been going back and forth on this one but now think it may be a wrinkle ridge though originally a possible scarp.

Thanks. I'm working on discriminating between ridges and channels.

It's not easy, Charaxa!

What I do when I'm not sure, is I try to find a perfect crater (so I am sure it is a crater and not a mound) and use the shadows on that to figure out where the sun is coming from. Once you have that, it should be possible to distinguish between channels and ridges.

I see lots of shadows there rather than cracks. It's quite tricky to see from a photo of a computer screen though. Have you had a peek at the image posting guidelines over here (http://forum.moonzoo.org/index.php?topic=7.0)?
: Re: Lunar Features - channels, cooling cracks, pits, domes

Too bad you can't see what I see. Yes, I saw the guidelines, but unless I take a snap of the screen I don't know of a way to show others what I see. I was quite surprised that IreneAnt couldn't see the crossed shovel and golf club 'marking' that I plainly see. And I'm surprised you (Jules) could see the boulders/partial ring of boulders I posted a few days ago, but not the collapsed roof I posted more recently. The ACT-REACT freezes my computer, as does the NAC viewer after 20+ minutes, even though I have 1 gig of RAM and a 1.8 gig processor. Too bad. I'll have to see if there's something else I can try to get around this problem. I don't know of a quick way to post a close/highly focused (near) image of the surface to show the features I find. Too bad.

We do sometimes "see" different things! It's a case of getting your eye in and it's not easy at first. The section on screen grabs is what you want in the link I posted. If you use Vista or Windows 7 it's easier via the snipping tool otherwise a good old fashioned screen grab will do the trick. If you need help just shout or send a mod a PM. :)

I'm using Windows XP, but there's no doubt that you are very encouraging. Perhaps I've spent too much time looking and reading interpretations of HiRise images from Mars :-) For me at least, it's 10+ times slower to use anything other than the NAC viewer. I'm interesting in surface processes - I'll work my way back and see if I can
'refind' a few things in screen grabs before plowing ahead again. But I am learning! :-)

Looks like an abandoned mining operation here. All that remains is the old sluice. I did see what might have been a few squarish or multi-sided boulders in this area - perhaps some columnar jointing near here, under all this debris?:

Another interesting pattern of outcrop/boulders?  I'd sure like to understand the processes that went into the 'sorting' that I see here. 2 rows of 3 rocks, relatively equal size and equally spaced.
The first image has a fish or whale skeleton outline. Something tells me that differential erosion was at play here. Perhaps an eroding out of the bedrock that has these characteristics as distinct harder layers, flows, etc?
Left of the first image, bottom mid-right of the second image.
The NAC viewer gives the best view.

I originally thought these formations were crater chains but now think they could be short wrinkle ridge-like items. Are they connected with the huge crater, some type of flow or impact creation. What do you think?

Hello Charaxa,

Interesting picture from Mars!  I always find it difficult to determine if these formations are convex or concave (ridge or trench).  If they are more trench-like, perhaps they may be some type of eroded secondary crater chain  However, if you click on the NAC photo strip and look at the similar formation above the one shown, it does look to have a flow front-like appearance, though I do not have a good eye for those type of details. May simply be running into a crater. So, I guess we need Irene or Stu to tell us if they are  inny or outy features  :)

I originally thought these formations were crater chains but now think they could be short wrinkle ridge-like items. Are they connected with the huge crater, some type of flow or impact creation. What do you think?

Hi Tom128,

These are definitely trough features. I am wondering if they are drainage troughs in impact melt ponds. That large crater to the right may have deposited enough melt outside to form relatively thick melt ponds. The close up view shows how smooth the area around the troughs is, supporting this interpretation. So, it may be that, after the surface of the pond cooled somewhat, some of the melt drained elsewhere, causing the roof to collapse or subside this way?

Or they may be secondary crater chains, but I am not sure from which crater.

In either case, they are not wrinke-ridge like features, which have positive topography (are a hill, not a trough).

Hope this helps

I took a look-see at these in the NAC and they don't look like secondary craters to me.  I'd go with "trough."  It is possible, though, that while not secondary craters, per say, they were made by an ejecta block plowing through the regolith and making the trough ... so they could be secondary features formed by the main crater.

Hi Irene and Stu, thanks for your input on the troughs. I had briefly thought of caved-in lava tube like formations but could not figure out if I was looking at an inny or an outy in the pic.  Secondary impact troughs is a cool concept.

Irene, cooling cracks on a relatively thin section of impact melt makes sense, especially during the extreme temperature changes on the Moon.  Reminds me of the effect of heating up a glass marble and then putting it in ice water. I do like the idea of running water on the Moon though and am still looking for the alien built reservoir  ::)

Hi Jules,

You know what is interesting about the bright areas is that they fall right in line with the melt flow and are quite wide. Nothing else of note on the melt flow area aside from that.  Could be impacts fortuitously hitting the bulls eye so to speak but seems a strange bit of luck and you would think they would have more of a crater shape. Maybe a shower of smaller debris hitting just right in those locations.  Hard to determine how deep they are. Very odd looking openings.

It's hard to see because of the very high contrast, but it looks to me as if the bright areas are a bit depressed with respect to the darker areas. That makes me think these are local collapses within the larger long sag channel. I wouldn't expect this kind of arrangement from impact craters, even secondaries.

I wouldn't have said impact melts can have flow tubes a year ago, but we have seen several examples in this forum already of melt migrating and causing the chill crust to collapse (here (http://forum.moonzoo.org/index.php?topic=62.msg9107#msg9107), for example). So, now I would say this is what we are probably seeing here.

Placidstorm, that is one incredible and violenty torn up area near those large craters.  I am not sure if what you have posted is a melt flow or rather a large and very interesting line of impact ejecta or melt splat of some kind.  There are numerous ejecta and secondary impacts all over the place.  It is certainly a great place to explore.  When you zoom way out you can see how violent the action really was.

Hi Irene,

Very interesting  :)

I was thinking that perhaps the dynamics of a narrow channel of melt flow widening towards the end where we are observing had some type of velocity change in the subsurface molten material causing pooling and hollow areas. Of course we do not know for sure which way the material was flowing but I am guessing in the direction of our sunken structures.

Very interesting, Tom128.

Wrinkle ridges tend to be much larger than this. So if this is a wrinkle ridge, it is telling us something about the scale of the deformation that formed it. Alternatively, it could be a flow front. I myself am not sure which it is, yet.

Hi Tom128,

I just took a closer look at that collapse tube (http://target.lroc.asu.edu/da/qmap.html?mv=eqc&mcx=-968232.36938&mcy=753255.15932&mz=13&ml=FFFB00TT (http://target.lroc.asu.edu/da/qmap.html?mv=eqc&mcx=-968232.36938&mcy=753255.15932&mz=13&ml=FFFB00TT)). It is in the middle of Mare Imbrium. So, it's definitely a collapsed lava channel. Very nice!

Hi placidstorm,

I think we are seeing the same thing here as in a post (http://forum.moonzoo.org/index.php?topic=4.msg11235#msg11235) I just made in the Crater Questions thread. That is, I think this is just classic ejecta texture, formed when particles in an ejecta clump interfere with each other.

Also, there may be a bit of "flow" happening, because the particles have a lot of horizontal momentum when they land and so can form landslides and dry flows.

But this is the most spectacular example of this I have ever seen, if that is indeed what it is.

The 64mp pic is to show the general area ( I think its west of Scalfger ) and all the stuff going on down there .
Zoomin round at 32m/p you can clearly see the black streak that caught my eye .
At 8 m/p it's looking like impact ejecta ( black).
at 2 m/p it's looking like it may be a collapse and the black is lookin more like a shadow.
And at .25 m/p looks like maybe possibly a lil hole or vent bout 10 to twenty feet big . Doubt I'm lucky nuff for it to be much more than a shadow but thoght I'd  throw it out there anyway .

Wow placidstorm, that is some great pics with annotation.  Sure Looks like something interesting is occurring.  Notice the small narrow tail of black something that moves South- or North in the case of the pics below- of where the crater or hole is (may be shadow).  Looking at the NAC photo strip there seems to be a round and lighter crater like object with this depression/channel running thru the middle.  The black stuff looks like shadow but have no idea what caused all this.

The channel kind of looks like a scarp.

This is your crater on Act . In red is a good marking crater  for orientation , the blue is your linear features .
I was thinking secondary craters due to the crater chain running up the left side of the pic . However I went in the wrong direction initially . This crater chain heads to the Northwest quite away but I'm not posting those because I think it's the wrong direction .

To go along with you and Geoff's images, they are infact images that belong together.  The feature you both are looking at is the northern portion of the Lee-Lincoln fault scarp near the Apollo 17 landing site.  The fault first cuts the basaltic filled Taurus-Littrow in the south, cutting straight north.....then when it hits the North Massif (the lighter area you see in the photo) it takes a sharp left through the highland material.  I'm currently researching these thrust faults and we're finding that they're globally distributed.

what did this, water or a volcano?

Hi Rocketpower and welcome to Moon Zoo.

This looks like a sinuous rille and is formed by volcanic action (there is very little water on the Moon). Rilles can be formed from lava flows or from the collapse of a lava tube.

It would help if you could post the latitude and longitude of the image so we could research this area.

There is a good article here (http://en.wikipedia.org/wiki/Rille) about rilles.
