While the tide was low, we clambered with the class along the slippery rocks, listening to our eccentric teacher share his vast knowledge of seaweed and kelp (peppered with humorous anecdotes). We then made our way over to our driftwood "classroom" where we sampled the plants we had just seen in dry form, along with a potluck of seaweed-themed snacks. Afterward, we combed the beach to collect a little bit of seaweed to take home with us.
The beach was abundant in one of our favorite seaweeds, nori
A common and pretty tasty seaweed on Northwest beaches, bladderwrack
(shown here drying in our kitchen... it smelled pleasantly oceanic for several days)
