Ice Age Arizona was a cool, moist environment, vastly different from today's desert, with Meteor Crater holding a deep freshwater lake for 40,000 years. This period supported Rancholabrean megafauna, including the giant Ice Age bear, *Arctodus simus*, and early humans, evidenced by mammoth remains found with artifacts. Join NHI and archaeologist Dick Ryan to explore Arizona's glacial past, its animals, and early human inhabitants.

Dick Ryan is an archaeologist with ten years of field experience in the American Southwest and a Master's from NAU. His primary interest lies in Paleoindian mammoth hunters, a topic on which he has published extensively. He also actively promotes Mata Ortiz Pottery.

Discover how astronomer Vera Rubin's persistence led to the groundbreaking discovery of dark matter, a concept now fundamental to understanding our universe. Despite initial dismissal and facing barriers as a woman in science, Rubin's work revealed that astronomical objects exaggerate gravity's grip, earning her the National Medal of Science and posthumous honors like the Vera C.
