OBSERVATIONS

This object sits on the flat ground just beyond the slope of eroded sediment that has built up beneath a small cliff. Looking remarkably similar to rebar used in concrete construction work, this is the only clear example apparent in this NASA image. Although there are what could be similar fragments elsewhere, partially buried.

POTENTIAL FOR AN ARTIFICIAL STRUCTURE

The similarity to concrete rebar is strong, which could indicate a site where ancient buildings stood but which met with obliteration that left little remaining.

COMMON EXPLANATION

This is geological and could be the remains of what was formerly veins of hard material encased in softer sediment that has since been eroded away.
