Image of the Grand Canyon in the southwestern U.S. is a mosaic of two Landsat 8 scenes from Oct 31 and Nov 9, 2013. Designated as a national park in 1919, the Grand Canyon has breathtaking views of unique geological formations that attract over 5 million visitors each year. Archeological artifacts have been found in the park that are nearly 12,000 years old. Recent high-flow releases of water from the Glen Canyon dam (northeast of this image) have moved sand along Colorado River and into the canyon. The sediments are helping to establish sandbars for fish and wildlife habitat and to protect archaeological resources. The Landsat satellite, launched in February 2013, is providing high-quality worldwide images of the landscape on a daily basis. Landsat serves as a valuable tool for all interested in monitoring the characteristics of the earth's surface.
