Detail of part of the northern area of map sheet # 78 Tun huang - This
shows the towers of the Han wall north of town along the Su-lo Ho. Stein
analyzed the roll of each tower. One can now use Google earth to look at this
area and then zoom in to bring the town and caves into detail. Then click on
some amazing photograhy that shows what the city and cave area look like.
Clearly there has been much more dramatic change in the100 years since Stein
was there than in the 2,000 years between the Han wall construction and his
visit.
