Epic dive at copper cliffs.
We found an octo perched up on top of a rock that was really cool, hope the photos turned out!
Found a nice horizontal Ridgeline on the wall that was stuffed with spaghetti worms and colorful invertebrates and longfin sculpin. Puget sound king crabs piled on top of each other mating.
I think I saw that tiger, it was camera shy!
