LANDSAT TM imagery (July 30, 1990) over the Ejina Region in Inner Mongolia, China, showing locations of the sites that we researched.

The Ejina Region, our study area, is located at the terminal of Ejina River. There used to be an oasis in the desert stretching southeastward from today’s oasis. Settlement ruins and archaeological features are mostly distributed over the old oasis now deserted.

Landsat satellite images are available from Global Land Cover Facility.
