I'm willing to bet, there is a large impact crater on the moon fairly close to where these "lines'.

These "lines" are inside a 15 km wide crater, on the wall of the crater, as you can see if you look at the whole image.

Yes....and just read the caption:
"Southwest of Rowland crater on the Moon's farside, a 15 km diameter unnamed crater exhibits many boulder trails on the crater walls. The boulders range from 1 m to 15 m across and mark a path downslope to the crater floor from a higher elevation."
What again is the mystery here?

The detail that can be observed in the enhanced images does not agree with the image description.

To me it does, if you understand that the enhancement doesn't change things, so a crater is still a crater and a rock is still a rock.
The tracks still look like tracks made by boulders, even after the enhancements, and if you see things differently then it means (in my opinion) that your perception of what you see in the photos is changed when you look at an image with more contrast.
That's true.

So, the camera doesn't lie, but as you don't believe in this photo, it means this is not the original...
The original image provided by NASA at al in my professional opinion is not the true original as captured by the camera onboard the orbiter. The original should appear close to what can be observed in the enhancements but would probably have been slightly lighter with better graduation of greyscale.
It's obvious it changes things, if it wouldn't nobody would use them.
A photo-enhancement of an image does change things as can be seen from the images posted in this thread.
My problem with these enhancements is not what they add, it's what they remove, and in this case (as in most uses of any "enhancements") it removes detail, so saying we see things better with less detail is not really true, we are seeing the same things with less detail, so they look slightly different.
The shadow-enhancement procedure, when carefully controlled, does not introduce additional detail but reveals detail which may normally be 'hidden', 'washed out' or 'flat' as can be viewed in the above original.
OK, could you explain why do you think that, what, on the original photo, makes you think of it? As for what you see on the "enhanced" image, seeing that you were the one doing the changes in the photo, how can you know if you weren't doing things to see what you wanted to see?
The objects that appear as tracks and boulders are in fact built structures. I have been researching surface detail on Mars and the Moon for a great number of years and feel confident and qualified enough to say that I know what I am talking about when it comes to interpreting what can be seen in an aerial image.
Perception of what is in a picture depends on the person looking at it, the perception is a human feature, not a photo property; in the same way as a colour-blind person would have a different perception of a painting, for example, some people may have different perceptions when looking at more or less contrasted images.
With respect, your last sentence is not correct. Perception of what is contained in an image that has good definition and a low contrast level can be just as revealing to a seasoned observer as an image that displays a high level of contrast.
I think it's a landslide.

A very large object is resting on the rim of the crater. Is this object part of a crashed spacecraft?
The image you posted was from photo AS17-150-23086 (although you forgot the "150"), and you can see in the map below the area that was captured in the photo.

I cannot see how this location is the same location as the spacecraft anomaly shown above but there are some very interesting features showing in the enhancement.
Do you notice anything specific about the content in the image?
Disregarding the enhancement procedure applied to the image, do you feel that the image has been amended in any way to diffuse the content?
An oblique view of a rim of Guyot Crater on the lunar farside, as photographed from the Apollo 16 spacecraft in lunar orbit. The coordinates of the center of Guyot Crater are 116.5 degrees east longitude and 10.5 degrees north latitude. Note the black coloration which appears to be lava flow down the side of the crater rim.
According to the map, that photo doesn't show Guyot crater, so someone (you, me or NASA) is wrong.

No.
