Sunset Bay State Park was named by Thomas Hirst, an early settler in Coos Bay. It was used by fishing boats and other shallow draft vessels as a harbor for protection against violent ocean storms. Aside from serving as a recreation area with hiking trails, recreational beach and boat launch it is incredibly rich, mid to high tide zone area.The mid tidal zone is flooded for few hours every day during each high tide. The organisms there must survive wave action, currents, and exposure to the sun. The mid tidal zone is inhabited by sea anemones, starfishes, chitons, crabs, green algae, and mussels. Marine algae can provide shelter for such organisms as nudibranchs and hermit crabs. The same waves and currents that make the life in the mid tidal zone so difficult bring in food to the filter feeders and other tide pool animals.
