Unusual zeolites were found in a vacant lot that exposed vesicular Miocene Columbia River basalt in the 1970's on the corner of SE Lava Drive and SE 17th Avenue within the town of Milwaukie, Clackamas County, Oregon. The site was first found by Russ Kenaga in 1970 shortly after the site had been leveled for a building lot. Overgrowths of erionite-Ca, offretite, and levyne-Ca produced "hub and wheel-like groups" along with radial groups of flat-topped stilbite. The "hub" consists of hexagonal white silky offretite needles that surround brownish-orange hexagonal erionite-Ca needles. Colorless hexagonal levyne-Ca plates formed epitaxial to the "c" axis of the "hub" resulting in a "wheel-hub" group that was all overgrowth with more white offretite. This is the only known site for these unusual combination of epitaxial growths.
The site is now covered by Waverly Greens Apartments, built around 2000, with a swimming pool where the best minerals had been found. Rudy Tschernich
