11-Nov-2001 -- This confluence is actually very easy to access since it's about 300m after an highway exit and close to a gas station.
The highway goes from Grenoble to Valence in the South East of France.
It was a cold sunday afternoon and I was driving to Aix en Provence to reach my workplace from my home in Grenoble.
I took four shots North, Souh , West and Eastward + 1 showing the GPS datas.
The confluence point is actually at about 50m on the back of the highway gas station as can be seen on the picture.
