The Pico mudslide of '69
Here's the Pomona Freeway mudslide photo from 1969. What kind of car is that?
The caption information provided by the Los Angeles Public Library is kind of sketchy. Here's what it says:
"Mudslide covering all eastbound and two of the westbound lanes of the Pomona Freeway, 2 1/2 miles east of Pico Rivera."
If you are interested, here's a link to the full record, which contains information about the photographer (Fred Garcia), and the fact it was part of the Her-Ex photo collection.
