The August general meeting will feature a talk by member Paolo Sanchez who will focus on large-scale landscape geology. The presentation should be helpful for understanding Earth science, and to an extent, minerals, from the viewpoint of the window seat of a plane. While flying across the state and the country, Paolo took many pictures of geologic landscapes. He plans to talk about prominent geologic features such as the San Andreas Fault, Cascade Volcanoes, and the Colorado Plateau. We hope to see you there!
This program meeting is at 7:00 p.m. at Fellowship Hall of The Santa Anita Church, 226 W. Colorado Blvd., Arcadia, CA 91007. Come to learn and make new friends; open to the public, free admission.
Flint Knap-In and Paleo Tool Demonstration at Chilao School in Angeles National Forest
The July 2022 Field Trip will feature an educational visit to Chilao School, 40 minutes from La Canada. (Note that Chilao School and Chilao campground are different locales.)Chilao School is located next to the US Forest Service Chilao Fire Station. To get to Chilao School from La Canada, take Angeles Crest Highway 25.1 miles to the Chilao Campground loop. Turn left into the campground. Drive .9 miles past the Little Pines and Manzanita loops and turn left at Mt Hillyer Road (3N141). Proceed down 3N141 for .5 miles to Chilao School. The one room school is on the right BEFORE you get to the fire station. Some of the roads may not have names on them, so please look at the map before starting your journey.
Though the field trip is Saturday only, we’ll be camping ¼ mile down the road at Chilao campground on Friday night so we can get an early start on Saturday. There will be a potluck at the school or campground on Saturday night. Expect daytime temperatures in the 80’s and nighttime lows in the 50’s. If you want to camp overnight, you should arrive ASAP on Friday afternoon to claim a campsite. Better yet, arrange with someone who is going to be up there on Friday morning to reserve you a spot. Campground use is heavy especially in the summer. The cost is $12 a night. Water is provided along with a vault toilet. Note that the Station Fire ravaged Chilao about 13 years ago and new trees are now starting to repopulate the area.
We’ll be learning how to make spear tips, arrowheads, hatchets, and knives similar to what prehistoric man used thousands of years ago. This paleo tool get-together is casual; there is no schedule for instruction, hence there is no official meet up time. You can arrive and go when you please. I recommend getting there by 10AM.
I’ll bring obsidian slabs to practice on. You can contact me at rexch8@yahoo.com.
There is no charge, but a small donation to the nonprofit Redbird/Chilao Visions is recommended. Our hosts are Corina Roberts, founder of Redbird, and Gary Pickett, flint knapping artist.

Obsidian is a popular lapidary material to collect and cut. Join Pasadena Lapidary Society at the April general meeting, as lapidary artist Terry Wilson takes us on a virtual trip to Davis Creek and other obsidian collecting locations, updating us on collecting site regulations. Terry will share tips on how to inspect the obsidian in the field and back at home. She will also demonstrate how to line up, slab and cab the material to bring out the best of their unique optical properties, including how to cut a cab exhibiting the cat-eye effect.

A peek inside one of the display cases at the QIA PowWow 2021, held last month.
Pasadena Lapidary Society member Sue Pang shared some pics she’d taken during her visit in January to the annual QIA PowWow in Quartzsite, AZ. Members who didn’t make it out there this year were certainly there in spirit, as we’re not just lapidarists; we’re ROCKHOUNDS. For those who don’t know, the QIA PowWow is a rockhound’s mega candy store.
