Click the link below to view an ArcGIS map containing 60 photographs taken by Lowdermilk in August 1943 while travelling in Northwest China’s Gansu corridor (河西走廊).
I am wondering about the stele pictured in the photo above, but have not researched the question in earnest. Caption reads:
Kansu Province, China. The Corridor. On the divide between the Yellow River and the Gobi Desert stands the ruins of a temple built at a guard station along the Great Wall. This monument describes the happenings along the Great Wall. Aug. 25, 1943
