Glass Buttes Obsidian Field Trip (cancelled)

Trip cancelled due to Covid-19

Glass Buttes Day Trip

with Flint knapping workshop by Ryan Griffin and Geology talk by Bob Timmer

There are at least nine different types of obsidian in two massive mountains at Glass Buttes and Little Glass Buttes, just a two hour drive from Bend. Bob Timmer will tell us how it got there and Ryan Griffin, BLM archaeologist will show us how Native American’s crafted it into tools. After lunch members will receive a rock hounding map so they can collect up to 250 lbs (per year) of obsidian on their own.  Be sure you have good tires on your car. There’s obsidian everywhere! 

All participants must be vaccinated and members of ASCO

Details to follow from coordinator, Val Anderson
