This orthorectified wide-swath ASAR image shows the ridges of mountains on the French island of Corsica. Formed through volcanic explosions, it is the most mountainous island in the Mediterranean. Mountains comprise two-thirds of the island, forming a single chain. Monte Cinto is the highest peak at 2,706 metres (8,878 ft) and it has 20 other summits of more than 2,000 metres (6,600 ft). Visible to the south is the Italian island of Sardinia, from which it is separated by the Strait of Bonifacio.
