Landforms & Walls

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. The wall required laborers by the thousands to build 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 the landforms (Geomorphology) and arid environments it had to endure.

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

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