Explore nature's creative endeavors

Semken webImagine being an explorer in the 1700s and traversing our continent, eventually arriving in Arizona. The majestic mountain ranges and breathtaking vistas are coated with colors of crimson and sienna, and you marvel at the formations, something you've never seen before.

Join geologist Steven Semken, Ph.D, who will explain Arizona’s deep history, as we travel back in time and find answers recorded in its fossils, rocks, mountains and landscapes. He says the sublime landscapes of Arizona are rather young—geologically speaking—but they reveal rocks and fossils that have recorded a history of processes and changes that goes back nearly two billion years. By reading these rocks, fossils and landscapes, we can reconstruct the narrative of Arizona's deep history.

His lecture will include the origin of our magnificent Grand Canyon, the state’s copper wealth, the red rocks of Sedona and Monument Valley, the Mogollon Rim, and the Sonoran Desert community.

At 10:00 a.m., Monday, Jan. 6, professor Semken will be in PebbleCreek to discuss the nearly two-billion-year-old geological history of Arizona. Learn how the forces of earth created the dramatic topographical contours that are fascinating and specific to this great state.

Semken is a professor of geology and education. He earned his bachelor's degree and doctorate degree  at Massachusetts Institute of Technology, and his master's degree at the University of California, Los Angeles. He is a Fellow of the Geological Society of America, a recent speaker at Earthscope and past president and former speaker of the National Association of Geoscience Teachers.

Tickets to all Monday Morning Lectures are $5 at the door of the Renaissance Theater.
