Description: Marked here are many (but not all) of the Pyramid / earthen mound structures found near Xianyang in central China. To the East, near Tintong, I have also marked the site of the famous Terracotta Warriors of the first Emperor of Qin.
Also marked (with crosses) are a handful of sites that are not pyramids, but may still be of archaeological interest. Note particularly the arrangement of large earthen circles and rectangles near the river, about 55km West of Xian.
Purely for interest's sake I've added (with yet another symbol) the location of a large, modern, fortified complex in the vicinity of the pyramids; note the large steel towers around the perimeter.
Furthur patient examination of this region's imagery would almost certainly turn up more pyramids and archaeological sites.
