In the video, a yellow CAT excavator is seen digging up dirt and rocks from a riverbed. The excavator then lifts the dirt and rocks and dumps them into the bed of a nearby dump truck. The truck is also yellow and has a large bed for holding the dirt and rocks. The excavator's arm moves smoothly as it scoops up the dirt and rocks, and the truck's bed is filled with the material. The background of the video shows a cloudy sky and some greenery.
