Amazing urban and ceremonial centers such as Mesa Verde and Chaco Canyon became ghost towns. The population congregated to areas around rivers, more permanent sources of water. But the population was microscopic compared to today. When the Spanish under Coronado came into the Southwest in 1540, according to Coronado's chronicler, Bernal Diaz, the grass was "belly high on a tall Arabian". But it has been getting drier ever since. Visit the 4 Corners area today and see how much grass you can find in Monument Valley.
