Great pictures! The temple pyramids were the first skyscrapers of the western hemisphere!
The first picture is amazing, with the rays of the sun beaming out from behind the Temple of the Moon (yes it is the Temple of the Moon - I climbed both the temples of the Sun and Moon and I distinctly remember the temple of the Moon being at the end of the avenue of the dead as shown in the picture).
In two trips to Mexico a number of years ago, I managed to visit three of the sites shown:
1. Teotihuacan
2. Chichen Itza
3. Tulum
Of the three, Chichen Itza is in the best shape, the least restored, and most authentic looking. The temples of the Sun and Moon were heavily "restored" about 100 years ago using additional stones not from the original temples. If you look at the pyramid in Chichen Itza, you will notice that the left-most portion is unrestored. The archeologists in this case only restored the monuments with whatever falled original stones that could be found at the bottom of the pyramid and stopped when they ran out.
The best thing about Tulum is its location, right on the water, a rare thing for the ancient Mayans. It dates from the post-classical period and the workmanship in the structures is not of the highest quality.
My own Mexico photographs remain in that quant format called analog. Someday I will get them digitized.
