There's a vid for that ...
(Google Earth shows it as about 5,000' elev. around 50 km SSW of Grenoble)
From the YT description:
"La Salette is one of the most difficult and most technical airfields of the south Alps and few airmen venture there. Several accidents took place there, mainly because of side exits or too short landing, but there have never been deaths. Thus the main risk is to break some wood or to twist of sheet steel. The missed approach can be very late decided during flight, there is no effect of funnel as on other altisurfaces. We can decide even there once on ground if we arrive with too much speed at the top of the dome, which is shown in this video. The only difficulty in this case is to find the way to the axis of take-off in a place where the convexity of the profile leads to a very difficult visibility. The axis of landing is directed to 190 ° while the axis of take-off is 210 °. It is thus necessary in case of go around on ground, to turn at the top of 20 ° to the right if we do not want to break the plane (big slope to the left, bushes to the right!) to plan this eventuality, the mountain pilot will beforehand have taken a mark far off (summit) to facilitate this alignment. This video was shot in the morning of October 25th, 2017. We had left with my father this morning there for outdoor day mountain. The conditions being optimal this day there, my father wanted to make his first landing for La Salette by benefiting from my experience and from my friendly supervision. The approach was led well, but some kph of excess at the flare and a delay of application of brakes made us arrive too fast at the top of the dome. We shouted together "Go Around !" what proves that we were in phase. The fact of pushing the throttle control from idle to full gas all at once surprised the engine which began to suffocate, the full power returned only to the rotation. Incident to be meditated on the functioning of our engines (Continental O-200 on the speedjojo) which is not abnormal but which the brutal application of the throttle control under stress can engender."
