Now comes a study that concludes the route may have been much more direct, and made no use of the lake. Geologist Estuo Uchida of Japan’s Waseda University, co-author of the study, says that analysis of satellite images suggests the presence of an ancient canal that connected Kulen quarries pretty much straight to the Angkor area.
Over the years, quite a lot of academic brainpower has gone into trying to answer questions of which stones came from where. Have a look at the website of the Cambodia Stone Project, a fascinating consortium of experts from many countries of the world. Their job requires both a lot of field research and skill at theorizing and connecting dots. There are no records from the era to tell how stones were transported the long distances, and the temples’ bas reliefs of daily life aren’t much help, including only a few scenes that appear to show construction workers.

Probably the blocks were floated downstream to Beng Mealea to take their allotted places as the great monument rose in the 12th Century.
The quarry’s easy to reach if you’d like to take a look. About a kilometer past Beng Mealea on the road to Koh Ker, you come to a bridge across the stream. The quarry’s right beneath it.
