Universal Studios Hollywood - Rockslide

From 1976 Universal Studios Hollywood press release:
The giant rockslide is another of the thrilling special effects designed to give visitors a personal demonstration of how it's done in the movies.
As the tram passes below a rocky hillside on the Tour route, the earth grumbles and groans. All of a sudden the top of the hill begins to crumble and styrofoam boulders careen down the hill. The rockslide is completely recyclable and the entire process takes only 90 seconds.

I remember reading that the rocks were made out of foam and on rainy days the water would be soaked up by the rocks and then when they went down sly the water would explode onto the guests
