Before and after 1902, when the boundaries were drawn, Argentina expelled many Chilotes from their territory, as they feared that having a large Chilean population in Argentina could pose a risk to their future control. These workers founded the first inland Chilean settlement in what is now the Aysén Region;[55][56] Balmaceda. Lacking good grasslands on the forest-covered Chilean side, the immigrants burned down the forest, setting fires that could last more than two years.[56]
