"Uaxactun is located some 40 km north of Tikal, and although it is substantially smaller than Tikal, its span of occupation seems to have been about the same, with origins in the Middle Preclassic and abandonment by the Early Postclassic. Research conducted at Uaxactun from 1926 to 1937 established the basic cultural chronology for the central lowlands and was used as the starting point for almost all other chronological sequences in the region. It was founded on Uaxactun's available calendrical inscriptions, pottery sequence, and architectural development. As a case in point, the chronology of pottery forms and types at Tikal, owing to their similarities to those at Uaxactun, is founded on the work done by the original Carnegie research. "
Photos: Uaxactun is notable for an archaeological complex known as an "E Group" which was first identified here and served as a kind of astronomical observatory for marking the equinox and solstice paths of the sun. Such a complex takes its name from Uaxactun Structure E-VII-sub, an early classic structure dating from approximately 200 A.D. E-Groups were quite common in the area during the early classic: other examples are found at Calakmul, Tikal, and elsewhere.
Pots: Photos from the El Chiclero Museum at Uaxactun. These pots were collected by the Chicleros from a large number of sites in the area. Both Nikolai Grube and Sofia Paredes have documented the collection and their reports are available at the museum.
