Evidence of the presence of Paleo-Indians in the region has been dated as early as 2,000 BC. By 1,000 BC, a group emerged that is recognizable as the Yuman ancestors of the Kumeyaay, who continued to inhabit the northern portion of the Baja California Peninsula at the time of European contact. The Kumeyaay referred to the area now known as Rosarito as Wa-cuatay, which translates to "big houses" in the Kumeyaay language.
