After a few minutes’ silent observation, Sylvie drove on, cutting inland over flat land again. Then they were stopped on a levee, and looking over the Camargue, she said. Michel would not have recognized it. The delta of the Rhone River had been a broad triangular fan of many thousands of hectares, filled by salt marshes and grass; now it was part of the Mediterranean again. The water was brown, and dotted with buildings, but it was water nevertheless, the flow of the Rhone a bluish line out there crossing the middle of it. Arles, Sylvie said, up at the tip of the fan, was a functioning seaport again. Although they were still securing the channel. Everything in the delta south of Arles, Sylvie said proudly, from Martiques in the east to Aigue-Mortes in the west, was covered by water. Aigues-Mortes was dead indeed, its industrial buildings drowned. Its port facilities, Sylvie said, were being floated and moved to Arles, or Marseilles. They were working hard to make safe navigational routes for ships; both the Carmargue and the Plaine de la Crau, farther east, had been littered with structures of all kinds, many still sticking out of the water, but not all; and the water was too opaque with silt to see into. “See, there’s the rail station— you can see the graineries, but not the out-buildings. And there’s one of the levee-banked canals. The levees are like reefs now. See the line of gray water? The levees are still breaking, when the current from the Rhone runs over them.”

“Lucky the tides aren’t big,” Michel said.

“True. If they were it would be too treacherous for ships to reach Arles.”

In the Mediterranean tides were negligible, and fishermen and coastal freighters were discovering day by day what could be safely negotiated; attempts were being made to resecure the Rhone’s main channel through the new lagoon, and to reestablish the flanking canals as well, so that boats wouldn’t have to challenge the flow of the Rhone when returning upstream. Sylvie pointed out at features Michel couldn’t see, and told him of sudden shifts of the Rhone’s channel, of ships’ groundings, loose buoys, ripped hulls, rescues by night, oil spills, confusing new lighthouses— false lighthouses, set by moonlighters for the unwary— even ordinary piracy on the high seas. Life sounded exciting at the new mouth of the Rhone.
