The Ranch buildings burned in September of 1970 in a fire known as the Clampitt Fire. The fire burned a large area extending along the Simi Hills from northeast of upper Las Virgenes Canyon through Rocketdyne to Black Canyon. Here is a topo map of the 1970 Topanga fires.
If you are a geek about wildfires, or Santa Susana State Park (of which the Spahn property is now a part of) there is a scientific report on the subject HERE (PDF).
