Here There be Dragons- New Title and Edit

[brynmawr1]

At the edges, the fabric frays. 
Rivulets of water wander through sage grass like loose threads.   inverting the metaphor here might work better, i.e. ...loose threads wander like rivulets...

Burned out cars and abandoned busses are strewn like driftwood caught in a cruel tide
on the side of the 101. 

Several birch trees huddle together. 
Foliage mostly stripped. Exposed branches reach toward the tents pitched just off the road. 

The waves break strangely here. Sudden  consider moving this stanza to the first or near.  Introducing the waves, ocean earlier would help make some of the later imagery more relevant.
and violent. 

A crow’s skeleton rests on a small island of rock. Its wings outstretched. 

The sand is everywhere. 

Each grain working its way into the cloth of this odd tapestry. At the edges
where the fabric frays.

Hi Z,
I think you have a great foundation, but I need more footholds to follow the understory of 'the pitched tents' and the 'grain working its way' and why that is significant.
Thanks for sharing,
