Rocks represent immobility, right? But wait. Geologists have documented that red rock arches and towers move in response to far off earthquakes, wind, and even ocean waves. A Utahn research team generated predictions about the stability of these structures drawing upon not only movement sensors, but also experienced mountain climbers to get to the top of these tall towers of rock.
