Tracing Geological History Through Rocks and Minerals in Oregon’s Desert (Bend)

April 18 @ 7:00 pm - 8:00 pm


Join us for the final events of Oregon Natural Desert Association’s 2024 High Desert Speaker Series, featuring Alison Jean Cole—an author, rockhound, and lapidary artist. In this informative talk, Alison will showcase the rock and mineral treasures of Oregon’s desert. Obsidian, jasper, opal, and petrified wood each tell a unique story about the fascinating geological history of our region. Glimpses of Oregon’s earliest cultures can be traced through these stone materials, which have been sought after for thousands of years. Come learn how the practice of rock collecting has transformed over the centuries, and how it can be balanced with conservation efforts in our modern world.

ONDA is working to make our events as accessible as possible, and this event will feature an American Sign Language interpreter.
