At first I was thinking tornado, but reading the faded description it looks like these cars were arranged by a tidal wave. Could this be the aftermath of the Alaskan tsunami?
"guard over used car lot on Highway 101 Where cars were stacked up by tidal wave which ripped through the city early today following eathquakes in Alaska. Nine persons are known dead and 70 were injured. UPI TELEPHOTO" Is what it says, so I assume the earthquake in Alaska caused the tidal wave. https://www.history.com/topics/1964-alaska-earthquake https://www.popularmechanics.com/science/environment/a1967/4219868/
Yes it did. My fifth-grade teacher was going to college North of here in '64, and when he taught us about the earthquake and tsunami, he showed us that very photo, taken from one of the newspapers in Los Angeles at that time.
Yep, that is exactly the one I was thinking. I did a paper on tsunami's in a college geology class. I actually used this event as reference.
I remember one thing: Mr. Lutz (my fifth-grade teacher) telling us the floors at Western Washington State College (now WWU) were waving, as if you were walking on Jell-O. Fast forward to the Nisqually earthquake, and as I stood outside with my boss and co-worker, talking with the other business owners, it hit me, that the ground was waving, and I blurted out, "Sonofagun, Mr. Lutz was right! It is like walking on Jell-O!"
