  One of a set of three holes just below the track not far from Torca de Azpilicueta, the others being sites 4802 and 4803. This rift is the closest to the track, surrounded by 9 metal posts and barbed wire. Stones drop about 6m into an echoing space below. A 6m descent lands on rotting carcasses with the way on too tight.
