Earlier this week or last week (depending on where you read it) there was news that the Corpus of Maya Hieroglyphic Inscriptions Program is going to Yaxchilan to record that city's rapidly fading inscriptions.  Turns out that the Harvard News Office sent two reporters with the team.  Stories, updates, multimedia, and blogs can be found on the Scanning History website:

"Harvard News Office writer Alvin Powell and photographer Justin Ide are accompanying scholars from Harvard's Corpus of Maya Hieroglyphic Inscriptions Program (CMHI) on an expedition to Central America.  The CMHI's mission since its formation in 1968 is to record and disseminate information pertaining to all ancient Maya hieroglyphic inscriptions and their associated iconography."
