Some of Europe's most imposing mountains border France to the
southeast and southwest. East of the Massif Central, beyond the
Rhone-Saone corridor, the linear folded ridges of the Jura

and extend northward before turning east and entering
Switzerland and northern Italy. The French Alps, though high,
