There are three people visible in the image. They appear to be engaged in some activity, possibly related to the large pile of sand or gravel. The person on the left is wearing a blue shirt and appears to be standing close to the pile. The person in the middle is also dressed in a blue shirt and seems to be standing slightly behind the pile. The person on the right is wearing a white shirt and is standing further back from the pile. All three individuals are holding what looks like a shovel or a similar tool, suggesting they might be involved in the task of moving or handling the sand or gravel.
