WADI EL-QATTAFI: For a brief time, Jordan’s eastern desert blooms. The dozens of mesas commanding the bleak horizons are now skirted with vegetation. Through binoculars, these charcoal husks of dead volcanoes seem shrouded in green mist. Birds sing above yellow, red and purple wildflowers peeking up around flint shards and stone carvings. Many carvings are in the ancient Safaitic script, an ancestor of modern Arabic, but others are more recent: a drawing of a long-haul truck and “1999” scrawled in Arabic. Summer’s heat will soon burn the spring colors away, and return the “qaa” or plains in Arabic to the basalt black, sandy brown sand and sky blue, says Yorke Rowan, an archaeologist who has spent the past seven years studying the dawn of human civilization in Wadi El-Qattafi, Jordan. He has learned that this desert was grassland with topsoil where long ago humans stalked herds of gazelle and built homes, corrals and hunting traps. Semi-nomadic peoples built “Neolithic hamlets” used during seasonal hunting, shepherding and perhaps farming in the 6500 B.C to 6000 B.C. era, Rowan said. “There’s a lot more going on in this desert region that looks like such a blasted, empty territory to our Western eyes, including archaeologists who should know better, that we’re starting to discover,” he said. Sixty kilometers from the nearest city, Azraq, Rowan and colleagues in the Eastern Badia Archaeological Project have mapped thousands of these 8,000-year old stone structures, aided by a 21st century technology. Rowan drives out across the plain to a launch site for a drone, built and operated by archaeologist Austin Hill. Rowan throws it into the sky and Hill pilots the drone and its cameras out over the mesas. From the air, peculiar shapes form on the slopes of the black mesas: some circular, others kilometers-long. The large number of structures hints at an environment much more like the today’s spring bloom.
