As a result of intensified archaeological activity in northern Belize, and specifically the work of the joint British Museum-Cambridge University research project (directed by Norman Hammond), a variety of new data have been obtained on the prehistory of this region. Of the many sites that have been mapped, tested, or otherwise investigated in the past few years, one stands out as a major center of ancient Maya lithic technology. This is the site of Colha, located south of Orange Walk Town, along the highway between that town and Belize City. Personnel of the British Museum-Cambridge University Corozal Project began limited research at the site in 1973. As a result of efforts then and since, parts of this extensive site have been mapped, some stratigraphic tests have been made, and controlled surface sampling and lithic analysis have been initiated (the latter through the hard work of Richard Wilk). These investigations, although preliminary in nature, were sufficient to indicate that Colha had indeed been a significant center of stone tool production for the Maya, from Middle Preclassic through Postclassic times
