Visitors to Yosemite National Park in California’s Sierra Nevada Mountains often ask Park Geologist Greg Stock the same questions: “What’s up with this mountain range? Is it growing or shrinking? How old is it?” But 150 years ago, people considered the same questions, though the reason they were asking them happened to be very different—those visitors were out to strike it rich on California gold. Mountain ranges, those places where the horizon wins its war with the sky, appear so imposing that they demand explanation even to those unaccustomed to geologic curiosity. Many ranges have origins simple enough that school kids can recite the basic sequence of events. Two tectonic plates smash together like an extremely slow-motion car accident, with a crumple zone in the middle.
