Jay Slater updates: Spanish police reveal autopsy detail | World | News
Local media described the search area in Tenerife as over 250,000 acres of volcanic landscape, with terrifying 600 metre ravines and gorges.
Below the area where Jay last contacted his friends, the ground is completely covered by large cacti, trees and shrubs.
Even for trained experts with equipment, combing through the area proved extremely difficult.
This meant that some areas had to be searched from a helicopter, way above ground.
