Tuaba was the highest point on the river reachable by barges from the sea. It was only meters above sea level. There, cargo had to be offloaded and transported by road the remaining hundred clicks to the site. A key detail being that this entailed an altitude gain of some four thousand meters. Since said road had not existed at the beginning, the first cargoes, back in the early days, had been mostly road-building equipment. The lineup—some would call it a junkyard—of ancient, rusty hulks in Uncle Ed’s lot constituted a sort of archaeological record of that endeavor. Albeit a selective one, for many bulldozers had simply disappeared into swamps.
