Several men, some on horseback, stand in an open field. One man, possibly a priest, holds a cross. Some men wear western-style clothing and others wear native-style dress.
A man who may be a priest walks under a canopy. He is accompanied by four men who carry the canopy, four men carrying flags, and four women. A lake is visible behind the group as is a mountain in the distance.
