The Cerro Prieto geothermal field on the Colorado River delta in NW México, seen here in 1998, is a large producing geothermal field. This view shows the Unit 1 power plant. Exploration drilling began in 1959 and by the mid-1980s more than 100 wells had been drilled to depths as great as 3.5 km. Despite few surface volcanic features, the hydrothermal system covers an area of more than 100 km2.
