Operation Igloo White
Thousand of seismic listening devices were dropped on the Ho Chi Minh Trail by the US as part of the elaborate 'Igloo White' program.
The idea was to listen into night time activity on the ho Chi Minh Trail to coordinate attacks in regions where the trucks were heard.
Early in the war the sensors were dropped by hand over the Ho Chi Minh Trail
Vietnamese counter measures included moving the sensors and starting up truck engines carried on bamboo poles to random locations each night.
The sensors were dropped by jet later in the war as the Ho Chi Minh Trail became more dangerous.
NVA soldiers became adept at finding and moving the sensors.
The entire program was controlled by Task Force Alpha, located at an ultra secret base in Nakhon Phanom, Thailand.
Technicians used the largest computer in the world at the time to analalys data received from the sesors to try and predict when and where the trucks were heading.

The Phanop Valley was a natural choke point because trucks where forced to drive through a small opening in the karst rock formations.
The karst in the Phanop Valley is visibly shattered by the relentless bombing that targeted it.
At regular intervals along the Ho Chi Minh Trail were way stations which housed hospitals, repair stations and protective bunkers for the trucks.
A truck axle dragged out of the jungle south of Ta Oi.
There were up to 70 such way stations, called 'Binh Trams', stretched out along the Ho Chi Minh Trail.
