The end of History, they say. Every summer, thousands of tourists flock to the foot of the Pont d'Arc armed with beach towels, coolers and plastic buckets. The mouth of the Chauvet cave overlooks the landscape, below float a parade of canoes as groups of speleologists search for the slightest crevice in the rock. Children fray their own passage. Through the mists of time, the Chauvet painters beckon to us. Possible worlds, past, present and future. A dream chronicle of a drift along the river Ardèche, between caverns and canoes.
