This type of offering is left during the celebrations around the crops in the fields. This will assure them a good harvest during the year. February is the month dedicated to the Uncle, or devil, in the mining town of Oruro, and also to the Virgin of the Cave (Virgen del Socavon). Dancers, from all around the state, come to Oruro and flood its streets. The "Diablada of Oruro" is much more than a popular celebration during carnival. It is a dance dedicated to the misunderstood devil, or the Uncle, who lives in the guts of Pachamama or mother Earth. The miners say the Uncle is like a friend that protects them from any accident and helps them find their minerals. The dancers dance for many hours through out the city and finally get to the church of el Socavon where they get on their knees to offer their dance to the virgin.
