March 11th 2023 Field Trip to Mt. Baker area (agate, dunite, gneiss, jasper, and jade)

On March 11th, 2023, we will be going to the Mt. Baker area for agate, dunite, gneiss, jasper, and jade. I’m thinking first to meet at Ol One Lane Bridge on the middle fork of the Nooksack River to collect Dunite, which is a “jade like” green rock.  It’s prevalent in the river rock and easy to collect.  (Note edited on Feb. 11: it was determined that the green rock is dunite and not diopside.  Primarily comprised of olivine.)

Then to move on to Swift Creek by Baker Lake for agate, gneiss, and possibly jasper and jade.

Details will be sent via e-mail to my distribution list 1 week prior to trip.

Presidents Message

  • From the Top of the Rock Pile …. by Kat Koch Our February was another good meeting. Almost 40 members attended, most of which displayed what they make or collect. It was interesting to see everyone’s interests. Plus, I always enjoy these types of meetings as we have the opportunity to talk and visit one another. We missed our three Young Tumblers, Mason, Bentley, and Jude. I hope we see you at our April meeting, where we have fluorescent rocks and minerals and anything else we can find that change color under black light. We scheduled this meeting as the

Meeting Announcements

  • General Meeting – Thursday, April 13th This meeting has been planned for April because the Kent, Renton, and Covington School Districts are on spring break, so all our Young Tumblers plan on attending this fun meeting as there is no school the next day. Bring your friends too. Topic: Fluorescent Rocks!! Not all rocks are what they seem. We have all heard about shapeshifters in sci-fi movies. How about very real color shifters? The club will have a collection of fluorescent rocks for everyone to see. It is interesting to see the different colors rocks become under short or long-wave UV lights. We will then examine members’ rocks and see what happens under UV light. Show ‘n Tell: Bring your rocks, and we will see if they change colors too. This is a fun meeting, so gather up your rocks that you suspect might be fluorescent and bring them to the meeting!!
