"It was like a scene out of a sci-fi movie: A behemoth threatens an innocent town from atop a cliff, shrugging off all capture attempts.
Only this real-life besieger was a 116-ton boulder, which gave indications in February 1979 that it might plunge onto Pacific Coast Highway and possibly squash a BMW or two, if not some beachfront architecture.
The innocent town was Malibu, so naturally elements of show biz were involved.
It was movie producer/ writer Robert Radnitz who led a campaign lobbying Caltrans to bring the big rock down from its 186-foot-high perch.
He was understandably nervous: His home lay in its potential path on the ocean side of PCH. Radnitz estimated that the hulk had slipped 20 feet in the previous two weeks.
PCH was closed to traffic, making it the perfect gathering spot for dozens of onlookers during the 40-hour drama.
A few watched from kayaks. One viewer was sculptor Brett-Livingstone Strong, who said he wanted a piece of the Malibu rock so he could fashion a mini-Mt. Rushmore: a 3-foot-high bust of then-Gov. Jerry Brown, alongside the words, "For President."
Yes, the same Jerry Brown who is now state attorney general. But the hunk of sandstone wasn't being cooperative. A 2,500-pound steel net was dropped on it by a helicopter, but efforts to loosen the boulder from above failed.
At one point, a fire hose was attached to a hydrant and aimed at the big rock. A continuous stream of water slammed into it for more than two hours.
The Caltrans contractor in charge of capturing the giant told The Times that he had come up with the idea after his father-in-law said to him: "Why don't you wash it down?"
A reporter asked if his father-in-law was an engineer. "No," replied the contractor. "He's an accountant." Alas, the hosing failed to bring down the boulder.
Finally, after more than a day and a half of struggle, an inch-thick cable was attached to the steel-webbed net.
The cable was fed through a pulley-like device on PCH and secured to a huge four-wheeled skip loader parked about 400 feet down the road.
Darkness was falling, "turning the boulder into a hulking silhouette," when the skip loader began to pull the cable, The Times reported.
At first, only a few fragments broke loose. Then a rumble could be heard.
