Samabaj -- An Underwater Maya Site

In the highlands of Guatemala is the deepest lake in Central America: Lake Atitlan. More than one site has been found in this lake, including Samabaj. Discovered in the 1994, this site has been likened to Atlantis, due to how it may have ended up in the lake. Samabaj even got noticed by National Geographic, which made a documentary on it.

Location
Samabaj is located in the southern part of Lake Atitlan (itself located in the Sololá Department) about 40 to 82 feet below the surface. (It changes.) Before it was submerged, the site was on an island. It is north of another site called Chuk'muk, which is on land.

There are differing accounts on Samabaj's discovery. The account in Arqueología Subacuática  says that it was discovered in 1996 by Robert Samayoa Asmus.

In 1994, he had found an artifact (a vessel) and decided to see what all he could find -- he came to think that there had been a community that was now under the lake. Two years later, he found the site. Four years later, he got the site registered as an archaeological site.

Name Origin
Samayoa is the creator of the site's current name: Samabaj is a mix of Samayoa and "abaj" -- "stone" in more than one Mayan language.

History
Samabaj dates to the Preclassic Period. Specifically, items from the site date to around about 300 BC to 300 AD. This makes them date to around the Late Preclassic.

It's possible that Samabaj was an important Preclassic Period community for the basin that the lake is located in. Based off of artifacts found (including the remains of people's houses,) the site was not only a place where people lived, but was also a place for religious pilgrimage. It may have been important during the time when another site, Semetabaj (which had enjoyed power for a time) was no longer a living community.

Samabaj's life as a community ended around the time the Preclassic Period was ending/when the Classic Period was beginning. That is, around 300 AD, the lake rose over the the land that Samabaj was built on -- a natural disaster may have been what made the water rise. (One possibility is a volcano erupting.)

Where did the people go? It's possible they went to another site: Chuk'muk. Around the time the Classic Period began, Chuk'muk got bigger -- and it may be because the Maya of Samabaj moved there. (Speaking of Chuk'muk: interestingly, in this period it became an important community in the basin that Lake Atitlan is in.)
