What does this number measure?
Provence's iconic white summit. Mont Ventoux dominates the landscapes of Vaucluse with its limestone slopes and often windswept summit. The 1 909 metres are an altitude above sea level; they do not measure the height of the whole mountain from the foot visible in the illustration.
The 1,909 metres are an altitude above sea level. The height between a chosen foot and the summit would depend on the foot and slope selected.
The illustration shows interpreted relief; it is not a topographic cross-section from which to measure the slope.
Compare the stated dimensions
The comparison uses the number in each fact sheet: altitude, height, diameter, length or distance, depending on the reference. Two values in metres do not necessarily describe the same property.
