Identification Help Please

[kikinit247]

I found this in a creek in Northwestern Washington. The rock is dry in the first two pictures and wet in the third. I cut a piece off and light shone through the green parts. Any help in identifying this unique to me rock would be much appreciated.

Thanks in advance,
