The largest body of water in Southeast Asia, Cambodia's Tonle Sap is a fascinatingly complex ecosystem of rivers, lakes, swamps, and islands. In the wet season it swells to about five times its dry-season size. Its people remain where they are: life simply becomes waterborne. It is, in every way, the heartland of the country, even if much of it is often not “land” at all.
These photos are from several trips around the Tonle Sap since 2007.
