    Today’s archaeologists can see underground without digging, map objects that are hidden beneath vegetation, and tell what animal was wounded by a spear point! Is this magic or the science of archaeology?

    The Archaeological Society of Central Oregon invites you to explore the topic of archaeology -- the study of people from the past. Archaeologists learn about past cultures by studying the artifacts left behind; a sherd of broken pottery, a stone tool, a broken wagon wheel. By uncovering and studying the evidence of past lives, archaeologists discover many things about their culture -- from what they ate and how they lived, to the environment in which they made their homes. Join us as we:

    Examine and analyze artifacts.

    • Understand these fragile cultural resources need to be protected.
    • Learn how archaeologists piece together the puzzles from the past.
    • Hear about technology that seems almost magical!

    “I’m an archaeologist, not a magician, but I can see why you might be confused.”

    Eileen Gose, Outreach Coordinator and Presenter
