Sentinel Guard

A bump of trees stands sentinel
like a grove of lighthouses
grown beside the shore.

Crumbly granite boulders
morph into sand millennia
from now to display a beach
ready for footprints erased by
each back and forth of waves.

A mound of trees grays
into spooky-fingered stumps
with nothing to protect them,
nothing to watch out for
like a lighthouse
succumbing to the sea.
