Geological Formation of Southwestern Canyons

Te creation of a canyon is a story of slow, patient destruction. In thee American Southwest, thee primary agent of this destruction is thee persistent flow of rivers - most famously the colorado River, but also the Rio Grande, thee San Juan, and countless smallar tributaries. Over millions of years, thee erosive power of these rivers has cut thraigh layers of sedimentary rock, exposing a vertical -sectiof of earts 'history.

Thee Role of thee Colorado River

The colorado River is the master carver of thee region. Its journey from Rocky Mountains to the Gulf of California nia has sculpted the Grand Canyon, Glen Canyon, Marble Canyon, and many others. The river 's ability to cut downward is coorn by its gradient, volume, and thee sediment it carrives. As the Colorado Plateau uplifted starting about 70 millionyears ago, thee river maintained its course, cutting deer and deeer inting risint - a process; 1s; FLt;
