Geological history

The region first saw volcanic activity about 11 million years ago, and since then has seen four separate episodes of volcanic growth and caldera collapse, the most recent of which began about 1.8 million years ago and culminated in the formation of the present caldera. The lake now fills a large part of the caldera, reaching depths of up to 600 metres.

The caldera-forming eruption is known as Los Chocoyos eruption, and ejected up to 300 km³ (72 cu mi) of tephra

Tolimán began growing after San Pedro stopped erupting, and probably remains active, although it has not erupted in historic times.

Several Mayan archaeological sites have been found at the lake. Sambaj, located approximately 55 feet below the current lake level, appears to be from at least the pre-classic period. There are remains of multiple groups of buildings, including one particular group of large buildings that are believed to be the city center.

A second site, Chiutinamit, where the remains of a city were found, was discovered by local fishermen who "noticed what appeared to be a city underwater". During consequent investigations, pottery shards were recovered from the site by divers, which enabled the dating of the site to the late pre-classic period (600 B.C. - 250 A.D.).

A project titled "Underwater archeology in the Lake Atitlán. Sambaj 2003 Guatemala" was recently approved by the Government of Guatemala in cooperation with Fundación Albenga and the Lake Museum in Atitlán. Because of the concerns of a private organization as is the Lake Museum in Atitlán the need to start the exploration of the inland waters in Guatemala was analyzed.
