Saltillo, Monterrey and Venustiano Carranza Reservoir, Mexico25.6N 100.3W
Two large cities can be observed nestled amidst mountain ridges in northeastern Mexico. To the east (lower right quadrant) is the city of Monterrey, the capital city of the state of Nuevo León. It has the second largest metropolitan area in Mexico.
West of Monterrey is Saltillo, the capital city of the state of Coahuila If the full Metropolitan Area is considered, making it the 20th biggest metro area in the country.
Visible to the north of the two cities, near the top edge, is the Venustiano Carranza Reservoir. Waters levels in the reservoir increased dramatically in early July 2010 due to incessant rains from Hurricane Alex, leading Mexican authorities to evacuate nearby towns for fears the dam would overflow.
