I've been thinking about this worms-like things on Mars and think it is most likely a pipe that NASA has made unrecognizable. I think smooth and glossy pipe was deformed this way.
Chandre I just checked out your tower link at Hirise... I searched that image number and I found two images...
In the 017043_1730 first image the inside of two "craters" look anomalous.... there appears to be a tall dark structure casting a shadow on the ground...
The other image you listed is 017043_2640 may have worm evidence... I couldn't make out just what type worm but the mouth open and another coming out is a bit visible and I wanted to share it with you and others...
We've been talking about repeated shapes/patterns and that we hould be highlighting these so that other seekers can keep an eye out for similar shapes in their work.
We have our delta-g's and worm patterns, angular rocks, rocks with antennas and protrusions and glyphs. Quite a lot already....
Now I am adding really big towers, here are four so far for everyone to enjoy
