Session: GSA Presidential Address and Awards Ceremony | Christopher (Chuck) Bailey <b><span>Life on an Active Margin: <i>Swimming Pools and Movie Stars</i></span></b></p> <p>Southern California is a region of both beauty and excess that lies astride an active and sometimes feckless plate boundary. Here more than 20 million inhabitants face a set of geological and environmental challenges, some well-known and dramatic while others are subtle but ever present. This address will include a personal take on the geology of southern California and then pivot to the critical role that geoscience must play in the future.
