Archaeological Excavations and Stabilization at Swordfish Cave

Swordfish Cave has long drawn in visitors with its alluring rock art including a realistic rendition of its namesake swordfish. However, viewers were inadvertently damaging the artwork because space inside the cave was very limited. As a conservation measure, Vandenberg Air Force Base asked Applied EarthWorks, Inc. to create a viewing area by excavating a block at the mouth of the cave. These excavations revealed a substantial archaeological deposit.

In this lecture, Clay Lebow will describe the archaeological excavations and the necessary measures taken to create the viewing area. Data from the site demonstrate that rock art on the Central Coast is much older than previously thought. Other data provide fascinating and unusual insights into the people that once used the cave and created the rock art.

Clay Lebow (MA) is a Registered Professional Archaeologist with more than 35 years of experience in the western United States, including 20 years along California’s Central Coast. He is a Vice President for Applied EarthWorks, Inc., a well-respected cultural resources management consulting firm. He is responsible for operations in our Lompoc office. From that office he has directed more than 170 archaeological investigations on Vandenberg Air Force Base, including a multi-year effort at Swordfish Cave.
