January 22, 2014 This sector of the Green River canyon in eastern Utah is known as Bowknot Bend because of the way the river doubles back on itself after a loop of nine miles. The river appears dark because it lies in deep shadow, 1,000 feet below the surrounding landscape. The yellow-tinged cliffs that face the rising sun give a sense of the steep canyon walls. The straight white line across the scene is the contrail from a jet liner. North is to the bottom of the image. The Green River joins the Colorado River, and their combined flow was responsible for cutting the Grand Canyon, about 200 miles away from Bowknot. International Space Station/NASA Buy Photo
