LIKE A LIGHTHOUSE DOMINATING the sea…. The Sea of Ice. The Drus seem to have conquered the Mer de Glace and stilled its waves, until the glacier no longer dares defy their steep mountain walls. Large pale stains, signs of recent rockfall, gleam like salt crystals deposited during some earlier epoch when the Sea of Ice flowed powerful and high, before it began to die down and to draw back, slowly and gently, leaving behind only vile shores of scree. Tourists arrive in uninterrupted floods to view Mont Blanc–merely to find its pallid summit drowned in a mass of satellite peaks, the Dome du Gouter and the Mont Maudit. The Drus, on the other hand, visible from nearly everywhere in the valley, their shape so easy to describe, are unmissable. You might say that a good portion of our planet’s inhabitants has seen them, if only from the seats of cars.
