Just in time for the U.S. National Park Service's Centennial celebration on Aug. 25, NASA's Multiangle Imaging SpectroRadiometer (MISR) instrument aboard NASA's Terra satellite is releasing four new anaglyphs that showcase 33 of our nation's national parks, monuments, historical sites and recreation areas in glorious 3D. Shown in the annotated image are Walnut Canyon National Monument, Sunset Crater Volcano National Monument, Wupatki National Monument, Grand Canyon National Park, Pipe Spring National Monument, Zion National Park, Cedar Breaks National Monument, Bryce Canyon National Park, Capitol Reef National Park, Navajo National Monument, Glen Canyon National Recreation Area, Natural Bridges National Monument, Canyonlands National Park, and Arches National Park. MISR views Earth with nine cameras pointed at different angles, giving it the unique capability to produce anaglyphs, stereoscopic images that allow the viewer to experience the landscape in three dimensions. The anaglyphs were made by combining data from MISR's vertical-viewing and 46-degree forward-pointing camera. You will need red-blue glasses in order to experience the 3D effect; ensure you place the red lens over your left eye. The images have been rotated so that north is to the left in order to enable 3D viewing because the Terra satellite flies from north to south. All of the images are 235 miles (378 kilometers) from west to east. These data were acquired June 18, 2016, Orbit 87774. http://photojournal.jpl.nasa.gov/catalog/PIA20889

Naked peaks, sheltered valleys, snowfields, towering trees, and alpine meadows make up the varied landscape of Sequoia National Park in California. Established as a National Park by Congress on September 25, 1890, Sequoia National Park is the second-oldest U.S. National Park, after Yellowstone. This national park borders Kings Canyon National Park. The Thematic Mapper sensor on NASA’s Landsat 5 satellite captured this true-color image of Sequoia National Park, outlined in white, on October 22, 2008. Sunlight illuminates southern slopes, leaving northern faces in shadow in this autumn image. In the west, deep green conifers carpet most of the land. These forested mountains are home to the park’s most famous giant sequoia trees. Sequoia National Park sits at the southern end of the Sierra Nevada mountains. Terrain alternates between extremes, from peaks such as Mt. Whitney—the highest peak in the contiguous United States—to deep caverns. The rivers and lakes in this region are part of a watershed valuable not only to the plants and animals of the park, but also to farms and cities in California’s Central Valley.

It has to be one of America’s most diverse national park landscapes. If you walked from west to east across Olympic National Park, you would start at the rocky Pacific shoreline, move into rare temperate rainforests and lush river valleys, ascend glaciers and rugged mountain peaks, and then descend into a comparatively dry rain shadow and alpine forest. From the beach to the top of Mount Olympus, you would rise 7,980 feet (2430 meters) above sea level. Situated on the Olympic Peninsula in northwestern Washington, these lands were first set aside as a national monument in 1909 by Theodore Roosevelt. Twenty-nine years later, his cousin Franklin officially established Olympic National Park. International institutions have also made a case for treasuring this land, as the area was declared an International Biosphere Reserve in 1976 and a World Heritage Site in 1981. The park encompasses nearly 923,000 acres of wild lands, including 60 named glaciers, 73 miles of coast, and 3,000 miles of rivers and streams.

Alternately known as a geologist’s paradise and a geologist’s nightmare, Big Bend National Park in southwestern Texas offers a multitude of rock formations. Sparse vegetation makes finding and observing the rocks easy, but they document a complicated geologic history extending back 500 million years. On May 10, 2002, the Enhanced Thematic Mapper Plus on NASA’s Landsat 7 satellite captured this natural-color image of Big Bend National Park. A black line delineates the park perimeter. The arid landscape appears in muted earth tones, some of the darkest hues associated with volcanic structures, especially the Rosillos and Chisos Mountains. Despite its bone-dry appearance, Big Bend National Park is home to some 1,200 plant species, and hosts more kinds of cacti, birds, and bats than any other U.S. national park.
