'The story of the White Pyramid came about in the 1940s, when eyewitness reports, specifically from pilot James Gaussman, related the presence of an enormous "White Pyramid" near the Chinese city of Xi'an. If true, it was bigger than the Great Pyramid of Giza. The region was off-limits to Western tourists for many decades afterwards and once this restriction was lifted, many pyramids were found, but the gigantic "White Pyramid" was not amongst them.
A photograph of what was believed to be the White Pyramid, turned out to be one of a much smaller pyramid near Xi'an. So what was the White Pyramid? Had someone overestimated the dimensions of a smaller pyramid? The answer is a simple no. The photograph had nothing to do with the original account of the White Pyramid, and this is where the main problem has lain in recent years. The actual White Pyramid is Liangshan Mountain and it is as big as Gaussman and others had claimed it was.'
“The pyramid is about 300 meters high (other descriptions estimate 330 to 400 meters high) and roughly 500 meters at the base, which makes it twice as large as any pyramid in Egypt. The four faces of the structure are oriented with the compass points.” This observation conforms to what we have seen on the ground about Liangshan Mountain: it is a colossal pyramid, with four visible sides, holding the tomb of emperor Gaozong. It is difficult to determine the height of the pyramid. If measured from the platform with the twenty guards, the height is 160 meters; if measured from the base of the pyramid, the height is about 300 meters!
