Zeolites are abundant in vesicular Miocene basalt exposed in the Beech Creek Quarry, located 10 miles north of the town of Mt Vernon, and 100 yards east of the mouth of the East fork of Beech Creek with Beech Creek (Highway 395). The quarry was operated by the Forest Service in the 1960's for road building. The rock was very rich in zeolites, especially levyne with a white overgrowth.
The white fibrous overgrowth on levyne has been described as offretite and erionite. With time most of the richest rock has been packed away by collectors.
