White Sands Nestled between the San Andreas Mountains to the west and the Sacramento Mountains to the east lies the Tularosa Basin.

E.T. and the Kid Today, I have a challenge for you. Despite its relatively young age, the United States is a nation full of pop-culture character sensations.

The Bootheel and Other Salients Humans love the notion of organization. We’ve taken a globe and sliced it into a grid; then we filled that grid with nations, states, counties, and cities. Viewing the planet from space, our longitudinal and border lines are invisible. Some of the lines between entities make sense, while others are
