Optical illusion . . . or . . . Photo evidence of ancient Martian receding lake level?
NASA,JPL & pharmerphil's Photoshop 6 ^ | 1-11-2004 | Phil V. & Socks C.

Posted on 01/11/2004 1:03:15 PM PST by Phil V.

What (if anything) do you guys make of this pic. I've been experimenting with the raw stereo pics (left and right). I've been attempting to make my own 3D pics using Photoshop 6. I adjust the left pic for red and the right for blue. I then overlay them on a new pic of equal size (1024 pixels) and set the transparency of each layer to 50% then flatten the image and convert to jpeg. In this case I shrunk the size to 512 pixels.

Look at the "contour pattern". I do not yet have 3D classes and my stereoscope is at work. I can't tell if the "contour pattern" shows up in 3D or in stereo. If it does it is very suggestive of a pattern of receding water levels. What other action would create these contours (if they are real).

Here are the links to the original left/right stereo pics. The "contour patterns" do NOT show up in the individual left/right pics . . . only in the overlay.

Looks like we've landed in a bunker on the third hole.

The pattern looks like a Moire artifact produced by your process. But it certainly is interesting.

Looks like some sort of wind effect, actually.

I was particularly bored a couple of nights ago and read some of the academic papers arguing for Gusev as a landing site.

It wasn't really advertised as place where we could land on an actual lake bed; the bed, if there is one, is deeply buried under regolith, but the hope was that various meteor impacts would have thrown deeper material on to the surface from sedimentary layers.

Don't you mean "drop circles?"

Circular patterns are created in the Arctic in small pebbles and stone circles from freeze/thaw cycles.
But, this looks WAY too big to be due primarily to that, or if it is due to freeze thaw cycles it's interesting.

Wind does not have the ability to accumulate rocks at common elevations. Receding water and wave actions WILL wash the sand and lighter debris away and accumulate rocks at a common level. I'll report back when my 3D glasses arrive. Until then I'm under double tinfoil protection . . .

Please explain "aliased". (rotating props appearing to spin backward?) These are NASA left/right photos overlaid - their "data", not mine.

Looks like the furrows left when a farmer makes turn pulling a harrow plow.
When's the planting season on Mars?.....;)
