Wasserkraftwerk

there is no postbox here but one inside the train station building

This position is about the center of a small ca. 15 m long bridge. the small stream passing underneath towards the river drôme is also missing in the map.

slyghtly wrong location I would say. it is rather at the turn of the road that goes toward the bridge (chemin de pont rompu). so a couple of meters to the north west.

This summit on my rendering seems a little off the topological summit.

I could not find this guidepost and there is also one further up with the same name which I could find. My suspicion is that this hikingtrail is discontinued. Further up I could find markings on a very small trail going uphill. But coming from the top at Blaygnères guidepost this trail is not indicated and there is even a small fence.

There is a small river/canal/waterway totally missing on the map I guess. Right here it passes under the railway next to the path.
