Los Azufres geothermal field began producing electricity in 1982, the year this photo was taken. The power plant at well AZ-6 shown here is located in the southern (Tejamaniles) section of the field. Surface exposures here consist of the roughly 1-million-year-old Agua Fria rhyolite rocks. Exploratory drilling began at Los Azufres in 1976, and 67 wells had been drilled by 1998 in an area of 60 km2, of which 33 were producing electricity.
