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.

March 13, 2021 Field Trip to Sidewinder/Ord Mountain

March’s field trip will be a return to the Sidewinder Mountains.  High clearance or short wheelbase vehicles are recommended for this trip. 2wd is okay. Those with passenger vehicles might need to be shuttled when we get close to the collecting sites. We’ll be searching for both tri-color marble (pictured above) and blue marble.  Tri-color marble is a beautiful green, black, and white material and is perfect for yard rock and spheres.  It’s also a good beginner material for making cabochons. We’ll also explore tailings piles in the Ord Mountains for chrysocolla and malachite.  copper minerals

Our last stop will be to the Prime Cut Rock Show in Lucerne Valley.
