Miocene flows and pillow basalt make up to ocean cliffs, seastacks, and arches near Oceanside, Tillamook County, Oregon. Zeolites were first found on the beach at Oceanside by Aaron Weiting in the early 1990s and became well known by others in 1995. The best specimens are found in boulders along the beach and in the cliffs along what is called Tunnel Beach. Maxwell Point extends into the Pacific Ocean at Oceanside and during low tide people walk around it to the beach on the north side of the point. Since many people have become trapped on the north side of Maxwell Point during high tide, a tunnel has be dug through Maxwell Point above the high tide line so people can retreat. The beach on the north side of Maxwell Point has been called Tunnel Beach. Zeolites are found in boulders and in the cliff at the north end of Tunnel Beach. A 4 to 8 pound hammer is required to break the hard fine-grained vesicular basalt.
