rocks and foam

I'd never noticed these strange pink rocks at Trinidad Beach before.
 
The foam was caught in some tidepools. Quite thick in places.  Leaflady (Gail)

I can't tell for sure: but is the pink a type of lichen? The foam is interesting. My first thought is always pollution. What causes it?

If I had to guess, and I HAVE to, I would suspect that some form of algae bloom washed inshore...the immature stages of red algae (which is of great interest to health-food nuts because of the many minerals contained) are sometimes seen like this... not pollution if this is the case... in fact, red algae consumes pollution and is being studied for use in industrial cleanup operations...

Reminds me a little of the mouth of the Russian River...

It looks like a lichen, but I wonder if it would survive the inundation of salt if it were. Maybe it is some kind of water plant. Dunno.
