To begin our adventures in 2013, my wife, Laura, and I took a walk on the moon. Okay, well, not quite. Actually, we visited White Sands National Monument in New Mexico. Prior to our exploration of what seemed like another world, we surveyed the exhibits and learned about what makes White Sands so special. We learned that these beautiful gypsum dunes are constantly moving and changing. While some dunes move only a few feet per year, others are making strides of up to 30 feet per year. That just blew me away. The dunes that move the furthest are changing the most and do so as they gain and lose tiny particles of the gypsum every day. It happens little by little.
