The Aztecs were a group of allied city states who controlled much of central America between the 12th and 15th centuries.

If fieldwork in archaeology conjures up images of a bullwhip or heavily armed babes, this series is for you.
Four Stone Hearth: Caves, Graves, and AudioFiles
The Clovis Comet theory argues that a comet exploding over the Laurentide ice sheet about 12,900 years ago caused--or worsened--the megafaunal extinctions and led to the end of the Clovis big-game hunting lifestyle. This theory was debated at the recent Pecos Conference, a regional archaeology conference held annually in different places in the American southwest.
The videos taken by George Howard during the August 8, 2008 conference , include the slide presentation by Allen West laying out the theory, as well as videos from the extended debate afterward with physicist Mark Boslough, astronomer Carolyn Shoemaker, and geologist John McCone. The videos are in 10-minute pieces but you can also play them as a playlist.
Tantalizingly, some of the discussion has been edited out--the nanodiamonds data, which is currently in press. Fascinating stuff.
