It is indeed Chartreuse. There is also a "must-see" that presents "a magnificent view" of Chartreuse when it is actually Belledonne!!

Very pretty, but it's not the Vercors, it's the Chartreuse, Mont St Eynard to be exact.

The passage of the landslide is done with portage (SPD wedges) the ascent at the end of the landslide on the Mortier tunnel side is deteriorating (drought/crowd) the staircase kindly built by local lovers is badly damaged. Such a shame that this closed road is not rehabilitated at least for the passage of 2 wheels ... it would be enough, as in Italy, to put up a sign stating that this access is dangerous and that its passage is at our own risk 🤷🏻♀️
