What could this be??

So what in the world could this be a picture of?  Snow? soap in a pond?  Or sea foam?  or or

This is a cropped portion from a shot with a 6 megapixel camera.  The photo was captured in raw format, and a tripod and cable release used to minimize any camera shake or vibration.  This is sea foam, in all of it's beauty!

You folks from Port Orford - this was taken at your place!  I believe it is Agate beach.

The natural world continuously surprises me.
