Takalik Abaj was first occupied at the end of the Early Preclassic period. The remains of an Early Preclassic residential area have been found to the west of the Central Group, on the bank of the El Chorro stream. These first houses were built with floors made from river cobbles and reed-thatched roofs supported on timber poles. Pollen analysis has revealed that the first inhabitants entered the area when it was still thick forest, which they began to clear in order to cultivate maize and other plants. Over 150 pieces of obsidian have been recovered from this area, known as El Escondite, mostly originating from the San Martín Jilotepeque and El Chayal sources.
