Oregon Geological Snowflakes: Thundereggs on Oregon Field Guide

If you missed, check online for the Geologic Snowflake Hunters Flock to Oregon for Thundereggs episode on the Oregon Field Guide on OPB TV.

Thundereggs are the state rock of Oregon, and fascinating to collectors young, old, novice, and experienced. Producer Vince Patton and his crew showcased the Madras, Oregon, annual thunderegg digs on the Richardson Ranch just outside of Madras.

As a reminder, the Rice Northwest Museum of Rocks and Minerals, one of our affiliates and partners, has more than 1,000 thundereggs in its inventory, including the famous “Meatball,” an 800 pound thunderegg in the Northwest Mineral Gallery that has never been cracked.
