Of the 10 or 15 people I have shown this picture, ALL of them have
said they see lakes in that picture. I see lots of water (or something
very similar) in that picture too. It seems obvious that the terraces
are caused by lowering water levels.

The darker areas in that low resolution picture do give that impression, but
see my previous message quote of the caption, and (LOL) "Land of Lakes"
comment. Apparently, the higher resolution picture the caption author was
looking at, showed that "dark sand forms dunes" in those areas. (Decomposing
carbon-based organic matter in ponds and lakes that dry up, do tend to have a
darker color than surrounding areas.) And wow, look at all of those erosion
gullies radiating away from some of those hills like solar rays. It is -so-
very obvious that there was a lot more water on Mars in former days.

(Isn't it about time for the "Mars was always dry" people to stick their
collective head in a bucket of water three times, and like, pull it out twice?
