Flying over a previously unmapped area of Cambodian jungle in 2012, a group of archaeologists come equipped with special laser technology.

Now, the area of focus for these specialists was Phnom Kulen, situated in the Cambodian province of Siem Reap.

For the area’s thick woodlands served as an obstacle to charting efforts – not to mention something altogether more dangerous.
