Our transcription: This sign was put in place following a series of rock slides. Like mudflows, rock and debris slides are mass wasting events that take place in mountainous areas, but they move at an even faster rate of speed. Rockslides like this one are a major problem on highways built through mountainous terrain where the oversteepened slope of the roadcuts are especially susceptible to slide activity. Some rockslides travel only a few meters to the base of the slope, while in country with high relief a rockslide may travel hundreds or even thousands of meters before reaching the valley floor. And if the movement becomes extremely rapid, the rockslide may break up and become a rock avalanche.
