The pockmarked terrain of Pinacate National Park in Sonora province, shown in this enhanced satellite image, provides evidence of a violent geologic past.Among hundreds of volcanic vents and cinder cones are rare maar craters, formed when rising magma met underground water to create pockets of steam that blew nearly circular holes in the overlying crust.Approximately 300,000 people live within 40 km (25 mi) of the volcano earning it designation as a Decade Volcano by the International Association of Volcanology and Chemistry of the Earth's Interior.Legend has it that gods sit atop the volcano on thrones of fire and ice.We read every letter, fax, or e-mail we receive, and we will convey your comments to CIA officials outside OPA as appropriate.However, with limited staff and resources, we simply cannot respond to all who write to us.
Pico de Orizaba is part of the Trans-Mexican Volcanic Belt that extends roughly east-west across Mexico.The CIA is particularly interested in information about imminent or planned terrorist attacks.In cases where an imminent threat exists, immediately contact your local law enforcement agencies and provide them with the threat information.In the area shown, ancient sedimentary rocks were folded as a result of a tectonic collision that some geologists consider related to the Appalachian folding of eastern North America.
This mountain range is drier than the rainforest areas to the south. The snow and ice-clad peak of Pico de Orizaba (also known as Citlaltepetl) boasts a summit elevation of 5,675 m (18,619 ft) above sea level, making it the highest peak in Mexico and North America's highest volcano.
The last recorded eruption took place in 1846; while the volcano is considered dormant at present, geologists continue to investigate the potential hazards associated with a renewal of activity.
