To give our Juniors more opportunities to explore geology and the lapidary arts, the Clackamette Club is always looking for new Junior participants and visitors are ALWAYS welcome!
Our Juniors have an instruction time at each of the regular club meetings. Juniors meet separately in the classroom next to the regular meeting room (Located in Kraxburger Hall of the basement of The Zion Lutheran Church in Oregon City). The Junior’s activity program begins shortly after the regular meeting begins at 7pm and lasts for approximately one hour. The Juniors program releases at 8 pm in order to accommodate early bedtimes. Juniors always are welcome to stay for the full duration of the regular meeting with parent or guardian.
So far this year the Juniors have learned:
The story and history of how the Thunderegg became the official Oregon state rock
The Oregon state gem stone: Sunstone
The Oregon state fossil: Metasequoia
The Oregon state rock: Thunderegg
3 Rock types rock Identification of as well as for-mation characteristics of each:
