Mount Ellen is a mountain located in Garfield County, Utah, United States. [4]
Mount Ellen's North Summit Ridge is the highest point in the Henry Mountains; it is also the highest point in Garfield County. It can be reached by a short hike from an unpaved road. These mountains were the last to be surveyed by the USGS in the lower 48 states. The mountain can be seen from as far as Mount Peale in the La Sal Mountains of eastern Utah.
Mount Ellen is an ultra prominent peak, meaning that it has more than 1,500 metres (4,921 ft) of topographic prominence, standing out considerably from nearby mountains. It stands in the watershed of the Fremont River, which together with Muddy Creek forms the Dirty Devil River, which drains into the Colorado River, and ultimately into the Gulf of California in Mexico.
The Paiute name for Mount Ellen was Un tar re. It was also referred to as First Mountain. After climbing to the summit in June 1872, Almon Harris Thompson named it for his wife Ellen. [5] Ellen Powell Thompson was also the sister of explorer John Wesley Powell. [6]
Over several days beginning on September 10, 1895, a detachment of the U.S. Army Signal Corps established the world heliograph record from stations atop Mount Ellen, Utah and Mount Uncompahgre, Colorado. [4] The record for visual signaling was established utilizing mirrors 8 inches across and telescopes. The flashing signals communicated over a distance of 183 miles.

Mount Nebo is the southernmost and highest mountain in the Wasatch Range of Utah, in the United States, and the centerpiece of the Mount Nebo Wilderness, inside the Uinta National Forest.

The Henry Mountains is a mountain range located in the southeastern portion of the U.S. state of Utah that runs in a generally north-south direction, extending over a distance of about 30 miles (48 km). They were named by Almon Thompson in honor of Joseph Henry, the first secretary of the Smithsonian Institution. The nearest town of any size is Hanksville, Utah, which is north of the mountains. The Henry Mountains were the last mountain range to be added to the map of the 48 contiguous U.S. states (1872), and before their official naming by Thompson were sometimes referred to as the "Unknown Mountains." In Navajo, the range is still referred to as Dził Bizhiʼ Ádiní.
Deseret Peak is the highest peak in the Stansbury Mountains with an elevation of 11,035 ft. It is located in the Deseret Peak Wilderness area west of Grantsville, Utah and east of Skull Valley Indian Reservation. It is the fourth most topographically prominent peak in the state of Utah. The site is a popular destination for hikers and backcountry skiers as the area is a contrast of the alpine wilderness with the surrounding desert basin. The trail that leads to the peak is easily accessible from Salt Lake City. The mountain offers views of the Bonneville Salt Flats, the Great Salt Lake, and the surrounding towns and mountain ranges. On a clear day, it is possible to see Mount Nebo, the highest peak in the adjacent Wasatch Mountains.

Mount Peale was named for Albert Peale, a mineralogist on the Hayden Survey of 1875.

Almon Harris Thompson, also known as A. H. Thompson, was an American topographer, geologist, explorer, educator and Civil War veteran. Often called "The Professor" or simply "Prof", Thompson is perhaps best known for being second in command of John Wesley Powell's Second Geographical Expedition (1871–1875), a federally funded scientific expedition that retraced the route of Powell's original expedition in order to further explore and map the drainages and canyons of the Green and Colorado Rivers in what is now southern Utah and northern Arizona. Thompson's diary of the expedition was originally published in the Utah Historical Quarterly in 1939. Through his work on the Powell expeditions and later as a geographer at the U.S. Geological Survey, he was responsible for naming many geographic locations in the Western United States. Thompson is also known for being a founding member of the National Geographic Society.
