MIDDLE EAST FEATURES - FOUND BY U2 SPY PLANE

In the 1950s and early '60s, with the Cold War at its peak, the United States flew U2 spy planes across Europe, the Middle East, and central eastern Asia, taking images of interesting military targets. Though the missions typically connected Point A to Point B, say an air field and an important city, in many cases the camera kept recording between those spots, capturing thousands of photos of the desert, steppes, fields, and villages below. Such a collection can represent a goldmine for landscape archaeologists. indexed or scanned. Knowing the potential insight offered by the U2 images, Hammer and Ur began sifting through the materials. By analyzing thousands of high- and low-resolution frames, they discovered many historical and archeological features, including prehistoric hunting traps, 3,000-year-old irrigation canals, and 60-year-old marsh villages no longer visible today. The work, which they published in the journal Advances in Archaeological Practice, represents the first archaeological use of U2 spy plane imagery--and a new and exciting window into history.

The hours of work paid off, revealing many important archaeological features, including prehistoric hunting traps called desert kites in eastern Jordan, an Assyrian canal system in northern Iraq, and marshes in southern Iraq, case studies the researchers highlighted in their paper.

Desert kites, stone-wall structures that date back 5,000 to 8,000 years, were used to trap gazelle and other similar animals. The dry desert of eastern Jordan preserved many of them, but agricultural expansion in western Jordan dismantled or destroyed many more. The satellite images bring them back to life, showcasing a web of diamond-shaped enclosures with what look like long kite tails, offering the best view, to date, of these important hunting tools.

The second feature, the canal system in northern Iraq, provides insight into how an early empire maintained its power and governed, Hammer explains. "The Assyrians built the first large, long-lasting, multi-cultural empire of the ancient world, so many people are interested in how they organized territory, controlled people, built their huge cities, and managed the land," she says. "The irrigation system fed the royal capitals, made agricultural surplus production possible, and provided water to villages."

Finally, the U2 images of southern Iraq present the layout, size, and environmental position of Marsh Arab communities in the late 1950s and early 1960s, many of which disappeared after massive hydroelectric dams in Turkey, Syria, and Iraq impounded the rivers, and especially after the government of Saddam Hussein deliberately drained the marshes. Before that, "people lived a unique lifestyle there for thousands of years, herding water buffalo, building houses and all manner of things out of reeds, living on floating islands of reeds, planting date palms, and fishing," Hammer says. "Now we can study the spatial organization, demography, and lifestyles of these communities."
