Oregon

The State of Oregon is located at the west coast of the United States of America. It has a long coast area, vast desert lands and high mountain ranges. It's state rock is the thunderegg. There are more than 100 locations known for t-eggs, most in the center and in eastern Oregon. Besides thundereggs, there are a lot of sources for great landscape jaspers, jaspers, petrified wood, wood replacements, obsidian, agates, carnelians, and so on.

Have fun by looking through my Oregon collection lodging all kinds of silicified material! :)
