Tidal variation in the archipelago is about
12 feet. Minus tides reveal the unique creatures that inhabit the intertidal
zone. Anemone, sea stars, chitons and limpets may be observed. Tide pool
walks are conducted throughout the summer at Fort Abercrombie, but many
beaches in the archipelago are worth investigating. Blue mussels and a
variety of clams are also found in the intertidal zone. However, never
harvest shellfish without checking for the possibility of paralytic shellfish
poisoning.
