A well known example of water's sculpture in the United States is the Grand Canyon. It is carved by the Colorado River over endless time into a spectacle.
Another example are the moonscape Badlands in western South Dakota. Here, water has worked in several ways to build up and to tear down. Sediments were deposited when the area was under a shallow sea. Later, when the Black Hills uplifted, streams and rivers deposited more sediments from the Hills. Sediments became soft rock formations. However, when streams and rivers diverted away from the area, depositions faded in favor of erosion to now constantly carve away these formations.
The Great Lakes formed when global warming caused the glacial continental ice sheet to retreat, carving out the Lakes' basins. The same glacier also carved much of the features of such states as Wisconsin, Minnesota and Illinois, creating flat lands, hills, valleys and countless smaller lakes. Before the glacier, much of middle United States was under an extensive shallow sea, resulting in layers of limestone prevalent in the area today.
Water also floods from rivers, enriching some adjacent land , eroding other land and creating new land. However, not all of water's work is above ground. Consider caves and the interesting formations within them; and, of course, there are the sinkholes that pop up.
Even the absence of water can become a sculptor of earth. The lack of rainfall for several years in the 1930s created the Dust Bowl in the Great Plains, eroding topsoil and displacing farms and their residents.
We enjoy, and utilize, water's sculptures for recreation, commerce and sustenance--and even just to admire the scenery. So, what is the value of water as sculptor of Earth? What do you think?
