For our June program we will have Dr. Bill Dinklage, Geology Professor at Santa Barbara City College, present “Minerals, Metamorphic Rocks, and Glaciers of the Around‑Manaslu Trek, Nepal Himalayas”.
The trek around the eighth tallest mountain in the world passes through metamorphic rocks of the Greater Himalayan Sequence. These include schists from Barrow’s garnet, staurolite, and kyanite zones, gneiss from the sillimanite zone, and diopside phlogopite gneiss. Dinklage will explain the origin of these rocks and show thin sections and hand samples of some of these rocks, as well as bioturbation preserved in black phyllite. He will also show some photos of glaciers in recession caused by recent climate change.
Our June member’s meeting will be in person at the Poinsettia Pavilion on Wednesday, June 24th. Social time begins at 7 p.m. and the meeting will start at 7:30. Members of the public are welcome.

Returning home from Brenda, Arizona, I have been working on the yard a lot, trimming bushes and pulling weeds. My gardener must have fertilized the weeds. After the show, I started transplanting succulents and cactuses for our next show, if we have one.

Sphere 1: Greenhorn Mountain rose quartz – collected from this popular field trip location in CA. I procured a 30-lb chunk from fellow rockhound Rob Sankovich’s yard, and I thank him for making the backbreaking hike back from the collecting area to the vehicles. Finished diameter is at 6.0-inches, showing the characteristic white streaks that in some pieces yields an asterism or star pattern. In this piece, I just got the streaks, and some orange hematite staining, but also some nice rosy coloration. I prefer when I can to keep the sphere material as unadulterated as possible (i.e. limited stabilization only, no bleaching, etc.) allowing nature to speak for itself.
Sphere 2: A massive chunk of Lepidolite with clear and smoky quartz and blue beryl (aquamarine). This material came from the Oceanview mine, in Pala, CA. Our club has headed down to this area regularly in late summer to sift through the dirt pile looking for tourmalines and such. Finished diameter is 4.2 inches. This one is fun one to hold and rotate to see the changes – the aquamarine was a surprise as I only saw it after making a few cuts into the rough.
Sphere 3: Silver lace onyx sourced from the Calico Mountains near Barstow, CA. This piece was fun to work with as it contains the classic onyx on matrix with some nice vugs; finished up at a nice 5.5-inch diameter. I am showing the obverse side as well to see the contrast between onyx and matrix. The Barstow field trip is typically scheduled in late spring before it gets too hot. Check with field trip leaders Chuck Borchard or myself to coordinate a potential trip Saturday AM 30 May 2020.
I made a sodalite and crystal necklace during lockdown! I’ve wanted to do some beading for quite awhile (since I keep buying beads and putting them in a drawer) and when the lockdown came around, even though I’m still working Monday through Friday, I had time on a weekend to put this necklace together. It was so much creative fun that I’m hoping to do it again and use some more of the beads that are sitting in my drawer.
