Rain of Stones from the Cliff..

This time we show when small stones fall by themselves from the top of the cliff during the summer, so the stones and sand stick to the top of the cliff when the sand is hot and when hit by wind they come loose from their place and slide down by themselves, and this can be dangerous for miners who are below.#climbing #buildingmaterials #mining #hardwork #rockclimbing #sandmine #construction #team #work #miner #landslide #working #excavation #excavator #teamwork #merapi #sandmining
