The land and estate was eventually sold by the Burdell family to Court Harrington. Harrington in turn sold it to the University of San Francisco, to be used as a Jesuit retreat.
"During the 1960s, the University of San Francisco sold Olompali several times. Each time, the buyers defaulted and the property reverted back to the university. The most famous tenant was the rock band Grateful Dead. During the Dead's brief stay it became a gathering place for San Francisco's rock musicians, including Janis Joplin and Grace Slick."
In 1967, Don McCoy leased Olompali, and started a hippie commune there called The Chosen Family. A fire caused by faulty wiring eventually destroyed the mansion. Finally in 1977, the State of California purchased the land and turned it into the state park.
