Jeep ride through the mountains of Real de Cartorce.As part of the workshop, participants were given a tour of Villa de la Paz where homes and schools reside on mine tailings. The UASLP research team from CEASSA, led the tour presenting the diverse activities they have accompished. Specifically, this research group is characterizing the mine tailings at Villa de la Paz and educating the communities and schools on how they can reduce their heavy metal exposure. The field trip ended at Real de Catorce, an abandoned mining area and sacred land to the Wixáritari (Huichol).  A doctoral student from UASLP presented his dissertation project in which he is working with this community to preserve sacred land as well as native traditions.  The workshop closed with four UASLP graduate student presentations on topics ranging from treatment of acid mine drainage to community health indicators.
