Naachtun
Naachtun is an archaeological site of the pre-Columbian Maya civilization, situated at the northeastern perimeter of the Mirador Basin region in the southern Maya lowlands, now in the modern-day Department of El Petén, northern Guatemala. Naachtun was a major center of the region by the late Formative Period, and was one of the few Formative Period Mirador Basin centers which continued to flourish into the succeeding Classic period.
Situated in one of the areas most remote from contemporary settlements, the site was first rediscovered and documented in 1922 by the American archaeologist and Mayanist scholar, Sylvanus Morley. The name Naachtun was given to the site by Morley, taken from a Mayan construction glossed as "distant stones", in recognition of its remoteness. Its ancient name was Masuul, and it was in the middle of the Classic Maya cities. The site is being investigated by the University of Calgary, where they have found that the site served as a link between Tikal and Calakmul, that were the superpowers in the Classic, and in constant wars between them, perhaps using Massul as a "Neutral Talk Place". A carved stela with the "Lady of Tikal" has been recently found there.

During the beginning of the Early Classic period, the establishment of a royal dynasty marked Naachtun's initial sociopolitical and economic development with Tikal. Residential areas reached their maximal occupation during the Late Classic period. Also during the beginning of the Late Classic period, a political shift occurred as Calakmul established their rule on the East Plaza of Group B. Relations with Tikal were cut during this time then re-established during the Maax 3 phase. By the Terminal Classic, Naachtun suffered a population loss leaving many of the residential structures abandoned. The population that remained settled in the Central and Southern Complexes located in Group B and remained there until the end of the 10th century.
Naachtun's population is believed to have used slash and burn agricultural methods as suggested by the archeological record.
