 The Puelches, being also nomadic, lived on the northern margins of Nahuel Huapi Lake and the surrounding forests in the Andean mountains, living off hunting and fishing.It is estimated that Mapuches started coming to the region before 1880 from Chile, leading to the imposition of their culture onto the other indigenous groups.Originally agricultural people, the Mapuches became nomadic upon arrival to the province due to the utilization of horses.
