The accident occurred last night as the red-and-yellow cargo truck made its way back from a party in the provincial capital of Santa Teresa. It fell about 200 metres into the chasm.
Rescuers equipped with little more than flashlights spent the night searching the ravine for survivors amid the twisted steel and large boulders. Authorities said bodies were found as far as 100 metres away from the impact site. There were no survivors.
Fedia Castro, mayor of the district where Santa Teresa is located, told Canal N television that rural farmers must rely on informal forms of transport because no public buses exist in the area.
The high-altitude roads of the Peruvian Andes are notorious for bus plunges, with poor farmers comprising many of the victims. Last year, more than 4,000 people were killed in such accidents.
