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:

1. Igneous

2. Metamorphic

3. Sedimentary

An introduction to Gemstone, Mineral and Rock Identification. 

The juniors will also spend part of the hour designing the layout of a Jr's display case for the club’s annual show in October.

Jim Urbaniak is our Juniors Program leader. Jim has extensive experience as a teacher, speaker, and geology field trip leader throughout Oregon and Washington. He has taught field geology at Camp Hancock-Hancock Field Station and has lectured on topics including the Missoula Floods. In addition, he is the author of more than 60 earth science articles.
