Join us at the CAST Senior Center every Tuesday afternoon for our free virtual programs! Everyone is welcome to attend, and no preregistration is required. Presented by the Senior Learning Network. Come and discover a short history of Whiskeytown, Northern California as we learn how Shasta County became a center point during the California Gold Rush. The focus will be a deep dive to learn about the unique geologic formations that have been described as a “mess” by their own geologist. Shasta Bally, the tallest mountain, is made of decomposing granite that creates a special set of hazards, especially when combined with the devastating effects of the 2018 Carr fire. Come investigate what sets this local geology apart, the hazards it has created, and why we should study the landscape around us.
