Steam rises from fumaroles (foreground) of the La Primavera geothermal field along La Azufrera fault, which can be seen in the vertical rock-filled gully in the background. Note the person observing the fault for scale. The geothermal field at La Primavera has been explored by the Mexican Comisión Federal de Electricidad (CFE) and exploratory drilling began in 1980.
