The early to middle Eocene submarine basalts of the Crescent Formation form the
core and basement of the structurally uplifted Willapa Hills region of southwest
Washington. The formation consists of a thick sequence of predominantly subalkaline,
tholeiitic pillow basalts and breccias formed as oceanic crust and seamounts at a sea...
