06-Aug-2007 -- This confluence is quite close to my home and I determined to visit it on my next journey to the North. Google Earth was in this case the best satellite map to use to plan the approach, although misleadingly there is a World Wide Panorama entry at the confluence point for a local Wat (Wat Rachabopit), the Wat is not at 14N 100E on the WGS84 datum.
The approach to the point is very easy only the last 200 Meters or so on, good, unpaved roads, in fact you could visit the point and do all the necessary without leaving your vehicle.
However to get in the spirit of the thing I walked for ...Oooh, about 10 Meters. The land here is flat and cultivated I didn't wish to damage the crop (sugar cane seedlings?) the confluence point is about 8 Meters into the field.
The elevation figure -- 4 Meters and this a long way from the sea -- makes you think about how vulnerable much of the central region of Thailand might be to sea level rises in the future.
