During Carnival festivities in the Andes mountains, a local tradition consists in throwing white talk powder, spray foam and confettis to the face of others while drinking and dancing to the music of local bands.
A group of old gauchos celebrate carnaval in Abra Pampa, a small village north of Humahuaca (Argentina)
The word "gaucho" could be described as a loose equivalent to the North American "cowboy".
