I got an email from Aztlan about a blog for the excavation in Calixtlahuaca, so I decided to post more archaeological excavations web sites.  They tend to have pretty nice pictures of the places the mission is excavating. 

The excavation at Calixtlahuaca has a website (http://www.public.asu.edu/~mesmith9/Calix/) and a blog (http://calixtlahuaca.blogspot.com/). 

The Holmul excavation also has a website (http://www.vanderbilt.edu/estrada-belli/holmul/), although updated only very rarely.  It does have cool pictures.  There is also a nice website about the dig at http://www.vanderbilt.edu/exploration/news/features/maya_origins/news_maya_origins.htm.  The excavation of Cival also falls under the Holmul project.  If you remember, Cival made some headlines a few years ago when giant stucco deity masks dating to the Pre-Classic were found there.  It even made it to CNN, and National Geographic had a segment on Cival.  

The Palenque project's website (http://www.mesoweb.com/palenque/current_dig.html) used to be very actively updated, but it hasn't been touched in about 3 years.  However, it's still a very good website.
