Zeolites were first found in Miocene tholeiitic basalt near Cape Lookout, Tillamook County, Oregon by John Cowles (cowlesite) in 1961.
The best specimens were found in highly vesicular fine-grained basalt at the bottom of the quarry and in large boulders piled along the sides of the quarry.
During a storm, the weathered upper portion of the quarry collapsed, covering the best material at the base of the quarry walls.
It was not until the early 1970s that the site became well known by collectors.
Vegetation has reclaimed the quarry, covering the boulders with moss and tall trees. With effort, specimens can still be obtained.
