Hi, I'm new here to the forum, been lurking for awhile, and thought I'd chime in on this thread. I've always been extremely interested in Mars since I was a kid,
Here's an intriging closeup of PSP_001440_1255_RED which is described as "Channels on Dunes in Russell Crater". I find the channels very curious. The hypothesis by the MOC team definitely sounds plausible.
To a non-scientist, like myself, they remind me of when you roll a large snowball down a snow covered hill. The snowball leaves a trail, pretty much like those pictured, till it disintegrates. I wonder if they could have been caused somewhat in the same manner, but by clumps of Martian soil rolling downhill?
I followed the naming suggestion, however, I'm not sure how close the pixel coordinates are.
