Landforms & Walls

                   Rio Grande River, Texas-Mexico Border (credit: Wikipedia)

Construction of The Great Wall of China began in the 7th Century BC and stretched more than 5,000 miles across the borderlands and mountains of northern China. Laborers by the thousands were required to build the wall as it crossed high mountains, windy steppes, and the sandy deserts of eastern China. Much of that Great Wall now lies in ruin due to these landforms (Geomorphology) and general environments it had to endure.

Plans for constructing big walls are being pushed for the US-Mexico border which runs nearly 2000 miles from the Pacific Ocean to the Gulf of Mexico. Like its earlier Chinese counterpart, construction of this wall would have to cross mountains, grasslands, and deserts. However, a geomorphological obstruction exists for this wall, the Rio Grande River running 1200 miles along the Texas part of the border between the two countries. The river represents the entire length of the Texas-Mexico border starting at El Paso to Brownsville where it enters the Gulf of Mexico.

Satellite photographs, captured along the entire lenth of the US-Mexico border, were processed to create an animation running from west to east. The Rio Grande required more than half of the data visualization. If the economics of building a new 'great wall' doesn't create pause, the winding river course of this prominant river feature may prove its doom.
