SAN FRANCISCO -- A dozen Holstein cows grazing in a field north of San Francisco suddenly decided to act like lemmings: they ran off a 50-foot cliff. Motorists say they saw the cows cascade off the hilltop, with some of the bovines tumbling end-over-end down the slate-and-gravel cliff. Marin Humane Society spokesman John Reese says the young heifers probably were spooked by a noise, or by a dog or some other animal. The Marin County Sheriff's Department says a deputy euthanized two of the cows at the scene. The others were taken to their owners at Silveira Ranch and were checked by a veterinarian. A ranch owner said cows will sometimes break fences, but not run off cliffs. She said something spooked them very badly.
