This series of photogaphs documents the hypothesis that the three excavated surfaces that we call glacis were indeed so. A glacis is a surface prepared in such a way that water can pass over it without creating gullies or erosion. The original glacis, f50 and f109 was made of a local virgin soil called baqaya, which resists the penetration of water. The second glacis, f123 and f152, built in the Mittani period to cover part of the baqaya glacis, was made of packed mud called wahal. The third glacis, f241, built late in the Mittani period to cover the wahal glacis, was made of packed earth containing sherds. If these surfaces are true glacis, then we should see a smooth surface after exposure to a typical winter's precipitation and wind. The photographs show that each glacis is covered by a crust of wind-blown soil hardened by exposure to rain, but is not eroded. |
