A Geologic Tour of Australia, via Zoom, is featured presentation for Tues., May 18 Program Meeting; 6:30 p.m.

Join us for our May 18 Program Meeting as we explore Australia’s most iconic natural wonders and visit several geologic sites that are unfamiliar to most people. Our guests, Dick & Mary Pat Weber, are retired exploration geologists and will take us on the armchair trip. In 2007 and 2008 they spent a year on what they refer to as their “Rocks ‘n Crocs” tour of Australia looking at and photographing the natural features and geology of the largest country in Oceania.

For our May Rock of the Month talk, Mary Pat Weber will present an introduction to a lesser known member of the garnet family, the rare and highly prized green garnet, which gives emerald a run for its money.

The Tuesday, May 18 program meeting starts at 6:30 p.m. via Zoom. To join us, send an email to joenmar1[at]verizon.net in advance, using ‘PROGRAM MEETING’ in subject line, and request the Zoom meeting link. We hope to “see” you there!

Eastern Sierra Field Trip Saturday, May 15th, 2021

Forsaking the desert, we’ll head deep into the forests of the Sierra Nevada Mountains. The PLS May field trip will be to the Obsidian Dome area where we will study the products of volcanic activity near Mammoth Lakes, CA. Geologically speaking, this volcanic activity is thought to have occurred fairly recently in the summer of 1350AD. This is a one day trip.

We will start at Obsidian Dome–a plateau with some small hills on top, littered with various sized pieces of obsidian. Most of the obsidian pieces at the Dome have tiny gas bubbles and aren’t gem quality but the shiny glass pieces almost glow in the morning sun.  

We’ll head to Crowley Lake after touring the Dome to look for fist size chunks of obsidian and arrowheads in the hills overlooking the reservoir.

After that, we’ll stop at Hot Creek visitor center, visit the free hot tubs in the area and hopefully explore some mine tailings looking for minerals related to gold mining.

High clearance is recommended for this trip.

For more information, please contact Rex at rexch8@yahoo.com.  Please put “Obsidian Dome field trip” in your subject line.

Lavic Siding February 13th, 2021

Miles from Pasadena, about a third of the way between Barstow and Needles, is the sleepy town of Ludlow, CA.  Most of the time, people never even notice it’s there, unaware that a well known jasper collecting area beckons in the blistering desert heat.  Such is Ludlow most of the year. 

Ludlow in the dead of winter is totally different. The ground is stripped of vegetation, blown away as tumbleweeds, or consumed by moisture-loving denizens of shifting desert sands.  The barren landscape causes the jasper to magically appear on the desert floor waiting for us to pick it up.  February’s trip will be on Saturday the 13th, to the renowned Lavic Railroad Siding jasper location near Ludlow, CA.  Our meetup spot is 148 miles from Pasadena.  We’ll meet there at 9 AM. Late arrivals will miss the fieldtrip. Read on for further information.

All colors, shapes, sizes of jaspers and agates cover the ground at Lavic Siding.

Since this is a semi-local trip, it will be for one day only.  We’ll explore the traditional Lavic Jasper collecting areas and the brindle jasper location in the foothills north of Ludlow.  

Red, ochre, brown, black… jaspers, agates… one in back has some drusy.. all found in the vicinity of Lavic Siding.

A high clearance vehicle is required for this trip, but 4wd is always better. Attendees will need to sign a waiver of liability.   RSVP is required.  Please email rexch8[at]yahoo.com for directions, inserting LAVIC FIELDTRIP in the subject field of your email.
