Powell Butte Plume Agate`

What's now the Powell Butte Nature Park was once a place to collect this gorgeous mossy plume agate/jasper. It's an extinct Portland, Oregon volcano cinder butte. This material was around in the heyday of the 60's and is seldom seen even in old collections anymore.   Very colorful stuff and one of the all time favorites. -WET pic.-(2"x 3"/2 oz./5mm thk)   a couple fractures
