Humans have lived in what we now call the American Southwest for centuries, making a wide impact on the land, much of it visible from aerial and satellite photography. Nuclear detonations, housing subdivisions, oil exploration, hydroelectric facilities, solar power facilities, roads, mines, farms, ranches, cities, and towns have altered much of the land over the years. Over the past week, I took a virtual tour with Google Earth, and wanted to share some of these snapshots of the human landscape in Arizona, New Mexico, Colorado, Utah, and Nevada.
