In many areas inside the huge Hebes Chasma basin, there are these massive alien operation plants which have similarities to irrigation pumping stations, although upon very close magnification along the center section here, one can just make out areas that depict "cross section streets" or words that that effect. In the anaglyph below, the center data point springs into life a little better as you adjust your eyesight to the vast "scale" of the area. If you were standing anywhere in these images, you would be too small to be seen, so keep this mind and you zoom in.
This image captured not so far away, from the above two, is another example of the pumping station and oh so typical mime of their style, is the inclusion of "humor" in a slight but significant way. Humor (or a version of it) is quite prevalent in the designs and creations seen on Mars.
Truly a fascinating discussion of alien "emotion" as one begins to see the evidence unfold in many renditions and structures!
In high magnification anaglyph below, the details begin to really take shape and one can make out the size and direction of the main conduit with the shadow below its trajectory defining the scope.
