Tarim River
The kingdom of Kröran (Loulan), later Shanshan, was probably founded at a strategically-located walled town, near the north-west corner of Lop Nur, next to the then outflow of the Tarim River into Lop Nur (40° 9’ N, 89° 5’ E). The site of Kröran covered about with a Buddhist pagoda about high, numerous houses, and irrigation ditches.
