Improperly referred to as volcano, it is the highest mountain in Patagonia (4709 m) and the only one in Argentina with glaciers outside the Andes mountain
range. Acting as a guardian of the North of Neuquén Province, it is the source of countless tales and legends, and has always been regarded with respect and venerated by the local rural people as “Father Domuyo”.
According to its geology and morphology, the Domuyo is not a volcano, as are the small hills nearby, where remains of lava can be appreciated. In Domuyo, the presence of
ferruginous metamorphic schists, gypsum and petrified fish and ammonites account for the fact that –prior to the emergence of the Andes range- this place used to be the bottom of the ocean.

All the surrounding area acts as a kind of underground pot of boiling water, whose vapour manages to escape through the various hydrothermal manifestations. Research is being carried out in
the area, with the objective of exploiting and making better use of the underground steam reservoir for geothermal power generation as well as to boost tourism in the area.
Several translations have been attempted, but splitting the word “Domuyo” into the two Mapuche terms “dumdum” and “nuvun” is probably the most likely to be correct. The fast pronunciation
of these two terms merged into Domuyo, meaning “that shakes and grumbles”, accounting for the legends around anger and running away.
