[3] In the early 1900s, a white rancher paid the Pehuenche to graze his cattle in the valley during summer, but he later claimed that he owned the land.

Thus, began a century-long dispute about ownership and land rights in the Galletué Lake area.

In 1987, a forest fire caused by the logging companies burned hundreds of acres of Araucaria trees.

However, legal challenges prevented the transfer of the land to the Pehuenche families living in the valley.

With assistance from the World Wildlife Fund and Chilean environmental organizations, the Pehuenche focused on developing the land for eco-tourism.
