We begin the new year by taking a deep dive into an even deeper subject: the mysteries of geologic time. We leave the turbulent present to visit the past, exploring the West long before it became the West. What stories would you hear if you interviewed the oldest rocks in Wyoming? How did pronghorn survive the Pleistocene when so many other animals died out? Grand Staircase-Escalante’s ancient scientific riches are under threat by the monument’s modern foes. The asteroid that created Arizona’s Meteor Crater may have also dammed the Grand Canyon. Meet the pioneering woman scientist whose insights into plate tectonics transformed the way we view our planet. You don’t have to clamber up cliffs to study geology; just wander around a Western city and examine the stone it’s made of. What does it mean to say that humans have lived here since time immemorial? Geology not only shapes the land, it shapes the people who live on and love it. Check out some excellent books on deep time.
