During the November lectures, Dr. Julia Costello, one of California’s most respected historical archeologists, will discuss new findings about early sheep ranches on San Miguel Island.

According to Costello, intensive ranching over the last 150 years drastically changed the island landscape. Erosion of the newly barren ground created sand drifts that covered the 1850’s era Niedever adobe and the Mills-Waters ranch that followed it. 

In 2009, Costello directed an archeological study of these sites revealing new information about who actually built the ranches and what life was like for those who lived and worked on this remote, windswept island. In addition, Costello will discuss findings that the Nidever adobe was a more substantial structure than previously thought. She will also demonstrate through aerial photographs how, in the end, some of the ranch remnants were covered by sands exposed from overgrazing.

Costello, who received her PhD from the University of California at Santa Barbara in 1990, has served as President of both the Society for Historical Archeology and the Society for California Archeology. She is also a member and chair of the State Historical Resources Commission. For the last 30 years Costello has specialized in researching sites relating to California’s European colonization through the early 20th century. She is currently an archeologist with Foothill Resources, Ltd. in Mokelumne Hill, CA.
