PRASBX Directors
As PRASBX Directors, Heather Hurst and Boris Beltrán have managed the study and reassembly of the mural fragments, directed new excavations at regional sites, integrated the use of lidar into project research, and continued to advance efforts in site stewardship and conservation. Together, they spearheaded a new collaboration with the National Museum of Archaeology and Ethnology, Guatemala, which created a collections room and permanent exhibition of mural fragments. Hurst is an Associate Professor at Skidmore College; Beltrán is a Research Associate at Skidmore College.
Dr. Heather Hurst has been a central figure on the San Bartolo-Xultun Regional Archaeological Project since 2001, when asked to draw the exposed mural during the first group expedition led by William Saturno. As an archaeologist and illustrator, Heather has conducted research at the sites of Bonampak, Copán, Holmul, Oxtotitlán, Palenque, Piedras Negras, and Tikal. However, the work at San Bartolo-Xultun, particularly its artworks and research on ancient artists’ materials, has been her primary focus for the past 20 years; she became Director in 2018. Through this interdisciplinary approach, Heather has earned the accolades of a MacArthur “Genius” Award and a Guggenheim Fellowship.
Lic. Boris Beltrán has been a member of the San Bartolo-Xultun Regional Archaeological Project since 2004 and became co-Director in 2015. He is an archaeologist with many years of fieldwork experience at Maya sites, including Copán, Honduras, and El Zotz and El Tintal, Guatemala. At San Bartolo, Boris excavated the earliest phases of the Las Pinturas complex and its murals associated with a buried E-Group. He has extensive experience working in Late Preclassic architectural contexts, artifact analysis, and mapping, as well as the excavation of monumental architecture at Xultun. Boris initiated investigations at the newly discovered center of Xulbe and explored nearby sites identified using lidar data.
