The Sedona Historical Society is hosting the next in its 2010 series of Living History presentations Wednesday, Feb. 10, 9 a.m., at the Sedona Heritage Museum.

This program will feature local geologist Wayne Ranney speaking on “What’s New in Sedona Geology.”

Ranney is a well-known geologist and author who has worn many “hats” in the American Southwest — backcountry ranger, river and trail guide, professor and geologist. He received his bachelor’s and master’s degrees in geology from Northern Arizona University in Flagstaff. Ranney has traveled the world visiting over 75 countries as well as both poles of the Earth. He is an award-winning author who loves to share the complexities of Earth science with interested nonspecialists. His latest book is a fully updated third edition of “Sedona Through Time.” His other books include “Ancient Landscapes of the Colorado Plateau,” “Carving Grand Canyon,” and “Images: Grand Canyon.” Ranney is well known in the Verde Valley and is an engaging lecturer and storyteller who makes Earth science come alive for all who hear him.

After the program, Ranney will be available for questions and refreshments will be served. This is a free public event.

Every year, the Sedona Historical Society presents a series of Living History talks. Speakers will include descendants of pioneers, long-time residents with historical stories to share or other storytellers about history. The Sedona Historical Society also operates the Sedona Heritage Museum. The museum is located at 735 Jordan Road in Uptown Sedona and is open daily 11 a.m. to 3 p.m. For more information on Living History or the museum, call 282-7038.
