CAMARILLO — After the 2013 Springs Fire stripped the foliage from the hillsides around CSU Channel Islands(CSUCI), Professor of Anthropology Colleen Delaney and six of her students unearthed something mysterious as they began excavating the area. Remnants of Camarillo State Hospital—which occupied the area from 1933 to 1997—were common, but this looked different.

“We found an unusual structure that was made out of volcanic rock and concrete,” Delaney said. “It did not match any of the hospital buildings, so we hoped it dated back even further. Based on some faculty/student research we conducted, it looked like a 1950s work building that didn’t match any of the hospital buildings.”
That unusual find launched Delaney on the trail of the mysterious structure, which she learned was part of a historic ranch named Rancho Guadalasca. She then wrote a book released in May entitled “Rancho Guadalasca: Last Ranch of California’s Central Coast,” by The History Press.
