If the previous dark streaks weren't strange enough, we find another, very similar-appearing form in the 2nd MOC image of this series.

This cliff is around 348 m (1140') high.

The dark shard shape seems to project from the top of the cliff.  It is roughly 266 m (875') long. 

 

Odder still, one can see rocky features of the underlying cliff bank through the dark shard-like item.  It is either transparent, or it is a shadow. 

We see a bit more structure at the top -- something like a bridge suspension cable.
