I see my Flaschenhals question remains unanswered.

Here is the next one:

When you ask people on the road in Italy what their highest mountain is many
will not know. Of those who believe they know, most will answer: Monte
Bianco. And, in a way, they are right.

A closer look on (French) maps reveals that the French/Italian border does
not run straight across the Alps' highest summit - 4807 m. Rather, it goes
with the Bosses crest, where also the "normal" ascent route goes, until
short before the summit is reached. Here, as the result of a shaky
French/Italian agreement of 1861, the border bends off and describes a
curve, in a distance of up to 600 m around the summit, to make the summit
entirely French, runs across a side summit called "Mont Blanc de
Courmayeur", before it joins the watershed Atlantic/Mediterranaen again.

Those who know this therefore usually label the Mont Blanc de Courmayeur as
the highest point in Italy, with 4748 m. Only a small minority of experts
ask themselves how high the border point is where it bends off from Bosses
crest. Vague reports say it is 4760 m.

So, question to you, scientists and experts to the front: How high is the
highest point of Italy?
