Foothills Speaker Series: Deep History of Arizona

Take a journey through nearly 2 billion years of Arizona's geological history, revealing how ancient forces created the landscapes we treasure today, with Dr. Steve Semken of Arizona State University. Through accessible storytelling and compelling visuals, Dr. Semken will reveal how ancient seas, volcanic eruptions, and climate shifts created everything from the Grand Canyon to the Sonoran Desert. This presentation offers everyone—from newcomers to longtime residents—a chance to understand the incredible forces and time scales that created the places we call home, providing new perspectives on familiar landscapes and deeper appreciation for why protecting these natural treasures matters for future generations.
