Measuring the Tetons and Jackson Hole

Caption: Wyoming's Teton Range looms behind a Global Positioning System (GPS) antenna in Jackson Hole that was part of a 17-year University of Utah study in which GPS devices were used to measure gradual movements of Earth's crust in Grand Teton National Park, Yellowstone National Park and surrounding areas. The study found the Teton Range and Jackson Hole are moving in unexpected directions, complicating efforts to forecast the likelihood of major earthquakes on the Teton fault.
