An avoidance system (40) is disclosed for operating a vehicle (38) on a pile (18) of material (16) on a worksite (10), the material (16) being released through an opening (20) at the worksite (10) and causing a disturbance zone (32) to form on a surface (30) of the pile (18). The system (40) has a sensor (42) positioned at the worksite (10) and configured to sense the surface (30) of the pile (18), and a processor (50) in communication with the sensor (42) and the vehicle (38). The processor (50) is configured to identify the disturbance zone (32) based on the sensed surface and a known location of the opening (20), and to transmit a signal indicative of the disturbance zone (32) to the vehicle (38).
