Info: ⚒️ Can You Dig It? The Great Earth Duel is Here! ?
Think you know your Bones from your Stones? It’s time to prove your grit!

Join us for an hour of high-stakes, low-strata competition as two local legends go head-to-head in the ultimate geological grudge match: The Great Earth Duel: Bone Seekers vs. Stone Keepers.

The Showdown:
Team Bone Seekers: Led by the infamous amateur paleontologist Greg. They’re looking for anything that’s been dead for 100 million years and has a story to tell. ?

Team Stone Keepers: Led by the legendary OAMS President Jim. They only care if it’s shiny, crystalized, and makes Greg’s fossils look "old." ?

Why you should be there:
Pick a Side: Join Greg’s "Team Trilobite" or Jim’s "Team Terminator."

Win Prizes: Help your team rack up points to win some "gneiss" memorabilia.

Get Schooled: See Greg and Jim’s favorite "toys" up close while they trade friendly insults and ancient facts.

Whether you’re a total "rock-ie" or a seasoned pro, we promise you won’t

Info: In this engaging presentation, Jim Urbaniak explores how rocks, minerals, and fossils serve as records of Earth’s history. Drawing from decades of collecting, fieldwork, and education, Jim highlights how specimens tell stories about ancient environments, geological processes, and the people who discovered them.
Through examples from his personal collection and broader historical context, this session connects petrology, paleontology, and stewardship, offering attendees a deeper appreciation for what rocks can teach us beyond their surface beauty.

Info: Have you ever wanted to find your own crystals and gemstones? Just a few years ago, Chris Lukas was a beginner just like you. Today, his incredible enthusiasm has made him a field expert, and he’s here to show you how to start your own journey!

This presentation is the perfect spark for new and junior rockhounds. Chris will share his "blueprint for a successful dig," including:

Essential Gear: The must-have tools for every young explorer.

Trip Prep: How to safely plan your very first outdoor treasure hunt.

The Pro Mindset: Why you don't need years of experience to find amazing rocks.

As Chris says: "If I can do it, any of you can do it too!"

Come get inspired and learn how to turn any hike into a geological discovery. Your first big find is waiting!

Info: Oregon is a legendary "Mecca" for all kinds of rock, mineral and fossil collectors, but how does the High Desert truly stack up against the most famous mineral frontiers? Join three seasoned rockhounds for a deep dive into the grit and glory of the hunt. Drawing on years of experience digging across the United States, our panel will compare the treasures found within the Beaver State to their prized specimens sourced from across the globe. They will share hard-earned wisdom on essential gear, field strategy, and the persistence required to unearth world-class gems right here at home.
