"Bingo", the Australian archaeologist said as he picked up and examined an ancient sandstone block. "This is a collapsed temple that was part of a bustling civilisation that existed 1200 years ago . . . it looks like the looters were unaware it was here," he said. Over the next few hours, Evans and a small group of archaeologists hacked through more landmine-strewn jungle and waded through swollen rivers and bogs to discover the ruins of five other previously unrecorded temples and evidence of ancient canals, dykes and roads, confirming data from revolutionary airborne laser scanning technology called lidar. The discoveries matched years of archaeological ground research to reveal Mahendraparvata, a lost mediaeval city where people lived on a mist-shrouded mountain called Phnom Kulen, 350 years before the building of the famous Angkor Wat temple complex in north-western Cambodia.

Evans, director of the University of Sydney's archaeological research centre in Cambodia, said the "eureka moment" in the discovery came weeks earlier when the lidar data popped up on a computer screen.

Heng Heap, a one-legged, chain-smoking former Khmer Rouge soldier, guided the expedition, hacking through the undergrowth and skirting landmines in the area where he knows every significant outcrop, stream and valley. Injured in three landmine explosions and wearing a prosthetic plastic leg, Heng Heap said he was surprised when the archaeologists, using GPS co-ordinates, pointed him straight to temple sites he never knew existed that were buried or hidden by jungle.

Fairfax Media recorded the archaeologists pulling away undergrowth at several sites to find pedestals from collapsed temples that were probably looted centuries ago. Guided by the GPS loaded with the lidar data, they stumbled across piles of ancient bricks. They found two temple sites where no carved rocks or ancient bricks could be found scattered nearby, indicating they have never been looted. Local workers at the site of the find.

Lidar works by firing rapid laser pulses at a landscape with a sensor, measuring the time it takes for each pulse to bounce back. By repeating the process, the technology builds up a complex picture of the terrain it is measuring. On Phnom Kulen, the data revealed hundreds of mysterious mounds several metres high across the mostly buried city."
