Grand Staircase-Escalante National Monument, Utah
The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured this natural-color image of part of the Kaiparowits Basin. This central portion of Grand Staircase-Escalante preserves rock layers primarily from the Mesozoic Era. The branch-like shapes are networks of canyons carved by rivers that dried up millions of years ago. The area receives far less precipitation than it did in ages past.
