Arches National Park is a national park of the United States in eastern Utah. The park is adjacent to the Colorado River, 4 mi (6 km) north of Moab, Utah. The park contains more than 2,000 natural sandstone arches, including the well-known Delicate Arch, which constitute the highest density of natural arches in the world. It also contains a variety of other unique geological resources and formations. The national park lies above an underground evaporite layer or salt bed, which is the main cause of the formation of the arches, spires, balanced rocks, sandstone fins, and eroded monoliths in the area.

The park consists of 310.31 km (76,680 acres; 119.81 sq mi; 31,031 ha) of high desert located on the Colorado Plateau. The highest elevation in the park is 5,653 ft (1,723 m) at Elephant Butte, and the lowest elevation is 4,085 ft (1,245 m) at the visitor center. The park receives an average of less than 10 in (250 mm) of rain annually.

Gamma-ray spectroscopy is the qualitative study of the energy spectra of gamma-ray sources, such as in the nuclear industry, geochemical investigation, and astrophysics. Gamma-ray spectrometry, on the other hand, is the method used to acquire a quantitative spectrum measurement.

Most radioactive sources produce gamma rays, which are of various energies and intensities. When these emissions are detected and analyzed with a spectroscopy system, a gamma-ray energy spectrum can be produced.

Canyonlands National Park is a national park of the United States located in southeastern Utah near the town of Moab. The park preserves a colorful landscape eroded into numerous canyons, mesas, and buttes by the Colorado River, the Green River, and their respective tributaries. Legislation creating the park was signed into law by President Lyndon B. Johnson on September 12, 1964.

The park is divided into four districts: the Island in the Sky, the Needles, the Maze, and the combined rivers—the Green and Colorado—which carved two large canyons into the Colorado Plateau. While these areas share a primitive desert atmosphere, each retains its own character. Author Edward Abbey, a frequent visitor, described the Canyonlands as "the most weird, wonderful, magical place on earth—there is nothing else like it anywhere."

Delicate Arch is a 52-foot-tall (16 m) freestanding natural arch located in Arches National Park, near Moab in Grand County, Utah, United States. The arch is the most widely recognized landmark in Arches National Park and is depicted on Utah license plates and a postage stamp commemorating Utah's centennial anniversary of admission to the Union in 1896. The Olympic torch relay for the 2002 Winter Olympics passed through the arch.
