The Ouachita (pronounced "wah-shi-tah") Mountains are fold mountains like the Appalachian Mountains to the east. During the Pennsylvanian part of the Carboniferous period, about 300 million years ago, the coastline of the Gulf of Mexico ran through the central parts of Arkansas. As the South American plate drifted northward, a subduction zone was created in this region. The South American oceanic crust was forced underneath the less-dense North American continental crust. Geologists call this collision the Ouachita orogeny. The collision buckled the continental crust, producing the fold mountains we call the Ouachitas. At one time the Ouachita Mountains were very similar in height to the current elevations of the Rocky Mountains. Due to the Ouachitas' age, the craggy tops have eroded away leaving the low formations that used to be the heart of the mountains.

Vertical quartzite and slate strata along the eastern flank of the Ouachitas

Unlike most other mountain ranges in the United States, the Ouachitas run east and west rather than north and south. This unique formation has been known to cause confusion to pilots flying over the region. Also, Ouachitas are distinctive in that volcanism, metamorphism, and intrusions are notably absent throughout most of the system.

Ouachita System (1889 words)
	Of this thousand-mile trend, only the 200 miles of the Ouachita Mountains on its northern flank, the Marathon Uplift (MU on the map) east of Alpine, Texas, and the small window of the Solitario near Presidio are exposed at the surface, giving little hint of the size of the system.
	The Ouachita System would still be a mystery were it not for the many wells drilled for petroleum (and some for water) that sampled its rocks, whose cuttings could be examined, and which could be cored to bring samples to the surface.
	The Silurian is represented by the Blaylock sandstone and the Missouri Mountain slate and chert.
