Trevelin (Spanish pronunciation: [tɾeˈβelin]; Welsh: Trefelin [tɾɛˈvɛlɪn]) is a town in the western part of the Patagonian Argentine province of Chubut.

[1] Evans had previously become well known for leading expeditions into the Pampas in search of new lands and mineral reserves, which had earned him the nickname 'El Baqueano' (meaning guide or scout).

One of the tourist attractions of Trevelín is the grave of Malacara, Evans' horse, who a few years earlier in 1884 had saved his master's life by escaping down a steep ravine when his travelling party was attacked by a group of indigenous people led by Cacique (chief) Foyel.

[4] The British arbiter was Sir Thomas Holdich (King's Surveyor General of India) whilst the interested parties were represented by Francisco Pascasio Moreno (Argentina) and Dr. Balmaceda (Chile).

The decline of the flour milling industry in the area can be dated to 1949 when the government of Juan Perón declared that the Chubut region was not appropriate for the cultivation of wheat, and therefore the land was turned over to the rearing of cattle.
