Before it was Camp Imelda, it was Sully's Hotel.
Earliest reference to Sully's Hotel is 1911. It's all gone now...

... then at some point Sully's Hotel burned down.

The Archdiocese of San Francisco bought the property and made it Camp Imelda for Girls. It operated as a girl's camp at least from 1940's - 1960's. No one is sure what year it opened or closed as a camp.
