What do you mean by "furrows"? If you are talking about those horizontal lines across the gullies than yes, I think those are the result of a bad joining of the photos or a result of using photos with those marks along one or more edges.

ArMaP, do you really believe yourself when you say that the 'furrows' in the pic below are due to bad joining between photos?
No, for that I would need the photos, the height data and the software used.
Can you replicate this so we know this CAN happen?
I hadn't notice that. In that case I think it probably is what I said above, the photos used to create that image already had those lines in them
Notice there is already a joint between the two images which can be discerned clearly BELOW the 'tracks' or 'furrows'.
I should have been clearer about it, when I said bad joining I did not meant to say that it was the result of a bad job by the people who had to do it, I meant to say that the resulting joining of the photos was bad, like when we have some photos with very different exposure levels that make joining them flawlessly impossible, if we change the levels on one photo to make it have a perfect join with the image on the left we may make a worse join with the image on the right.
So, if you say that it is due to 'bad joining', then...

This page has what looks like small sections of the photo you posted.
This page has what I think is part of the images used to map over the 3D data. When I saw that it was the Photojournal site I went looking for those images on your site, and you have them, PIA00424.png and PIA00425.png.

Hello Mikesingh and undo,
I would like to get into the Mars-subject a bit more so that I can talk about it and maybe even help in finding anomalies.
As a beginner on the subject, what websites would you suggest I read first?

Thanks, Beth! Wow! That Candor Chasma pic is mind blowing! I thought I'd go out trekking in the hills today. But darn! I've got to get working on your pic instead!

I'm curious to see if you find the same anomalies that i did.

Zooming in there are a couple of interesting shapes.
But at that scale, the most problable its just rocks what do you think?
