THE Museum’s Expedition to Piedras Negras, Guatemala, has commenced the fourth season at this Maya ‘Old Empire’ site. Mr. Linton Satterthwaite, Jr., the field director, is planning to concentrate on an architectural study of several new pyramid mounds, and two of these have been investigated so far.
In addition to the work at Piedras Negras, the Expedition has received permission from the Mexican government to make a brief architectural study at Yaxchilan, another important site on the Usumacinta River, some miles south of Piedras Negras. This reconnaissance should be finished early in the Expedition’s season.
