In the video, a man is seen wearing a face mask and a hard hat. He is kneeling down in a cave and appears to be examining the rocks. The man is holding a flashlight in his hand, which he uses to illuminate the area. He seems to be focused on a particular spot on the rock, and he is using his hands to feel the texture of the rock. The cave appears to be damp and there is water dripping from the ceiling. The man's actions suggest that he is conducting some sort of investigation or exploration.
