falling rocks
Cliffside debris descending
Falling rocks refers to loose stones or boulders tumbling down a slope, cliff, or mountainside.
The phrase appears most often on warning signs along roads and trails in mountainous terrain: Caution: falling rocks ahead.
The hazard is unpredictable—rocks may fall at any moment due to erosion, weather, or seismic activity.
