I will start with the festivity which is next on the yearly calendar, in this case:
FESTIVIDAD DE LA VIRGEN DEL AMPARO
Date: October 30 and November 1st
Sacaba is a small town to the east of Cochabamba, it is the capital of the Chapare province, which is to the northeast of Cochabamba. See the photograph:
Ok, now to the Festivity:
It starts with a party (verbena) which continues on the next day with a mass followed by a parade where the statue of the "Virgen de Amparo" or Virgen of Amaparo is taken through the streets of the town accompanied by folcloric dances. The following day there is a calvary (like I explained previously in the Virgen de Urkupiña) and the traditional ch'alla (blessing from mother earth) which is provided to different objects. In this case there are no special rocks which are used to achieve the desired object, like in the case of the Virgin of Urkupiña.
