This image of Devils Tower National Monument was created by combining elevation data and a digital photograph, captured over the landmark the same time by an unmanned aircraft system (UAS) in 2016.

This was an early morning capture as the sun was rising at Schwabacher's Landing, Wyoming. The heavy cloud cover shielded the Grand Tetons from full view, but as we sat there, a small sliver of the mountains peeked through the clouds just long enough to take a few shots.
