Adobe Mesa is a 7,475-foot-elevation (2,278-meter) summit in Grand County, Utah, United States.
Adobe Mesa is located four miles (6.4 km) east of Castle Valley, Utah, on land administered by the Bureau of Land Management. Adobe Mesa is five miles long northwest-to-southeast and two miles wide, with 400-foot vertical Wingate Sandstone walls. Topographic relief is significant as the summit rises nearly 2,300 feet (701 meters) above the surrounding terrain in 1.25 miles (2.01 km). Precipitation runoff from the mesa drains north into Professor Creek and south into Castle Creek which both empty into the Colorado River which is about six miles away. This landform's toponym has been officially adopted by the United States Board on Geographic Names. [2]
Adobe Mesa is composed of four principal strata of sandstone and siltstone. At the top is cliff-forming Wingate Sandstone which is the remnants of wind-born sand dunes deposited approximately 200 million years ago in the Early Jurassic. This overlays slope-forming Chinle Formation of Triassic age. Underlying Chinle is Moenkopi Formation which in turn overlays Permian Cutler Formation. There is an unconformity between the Cutler and the Moenkopi layers. [4]
Spring and fall are the most favorable seasons to visit Adobe Mesa. According to the Köppen climate classification system, it is located in a cold semi-arid climate zone with cold winters and hot summers. [5] Summers highs rarely exceed 100 °F (38 °C). Summer nights are comfortably cool, and temperatures drop quickly after sunset. Winters are cold, but daytime highs are usually above freezing. Winter temperatures below 0 °F (−18 °C) are uncommon, though possible. This desert climate receives less than 10 inches (250 millimeters) of annual rainfall, and snowfall is generally light during the winter.
The Titan is a 6,112-foot-elevation (1,863-meter) pillar in Grand County, Utah, United States.
Owl Rock is a 6,547-foot elevation sandstone summit located south of Monument Valley, in northeast Arizona. It is situated 7 miles (11 km) north of Kayenta on Navajo Nation land, and can be seen from Highway 163 perched on the east edge of Tyende Mesa, where it towers 1,000 feet above the surrounding terrain. Its nearest higher neighbor is Agathla Peak, 1.4 miles (2.3 km) to the east-northeast, on the opposite side of this highway. Precipitation runoff from this feature drains into El Capitan Wash, which is part of the San Juan River drainage basin. The first ascent of Owl Rock was made in April 1966 by Fred Beckey and Harvey Carter by climbing cracks on the west face, and then bolting up a smooth south nose to the summit. They employed 20 pitons and 14 bolts on this route called Warpath. The descriptive name stems from its uncanny resemblance to an owl when viewed from the east. This feature is known as Bee 'Adizí in Navajo language meaning "spindle", and this sacred place is considered to be a spindle left behind by the Holy People. A newer name for it is Tsé Ts'óózí, meaning "Slim Rock".
The Castle is a 6,387-foot (1,947 m) summit in Capitol Reef National Park in Wayne County, Utah, United States. This iconic landmark is situated 0.5 mi (0.80 km) immediately north of the park's visitor center, towering nearly 800 feet (240 m) above the center and Utah State Route 24. Precipitation runoff from this feature is drained by tributaries of the Fremont River.
Buttes of the Cross is two sandstone summits located in the northern reach of Glen Canyon National Recreation Area, in Wayne County of Utah, United States. The larger and higher south butte reaches an elevation of 5,642 feet, whereas the north butte rises to 5,569 feet, with approximately 0.6 miles (0.97 km) separation between them. When viewed from the north-northeast near Labyrinth Canyon, they align to form the shape of a cross, creating the appearance of a single butte. The name "Butte of the Cross" was first applied by John Wesley Powell during the Powell Geographic Expedition of 1869. A few miles further down the Green River, Powell finds that this geographical feature is two buttes when viewed from the east, so it was renamed Buttes of the Cross. Buttes of the Cross towers over 1,400 feet above its surrounding terrain. It is situated 6.8 miles west of Candlestick Tower, and one-half mile outside the boundary of Canyonlands National Park.
The Sixshooter Peaks are two iconic sandstone summits located in Bears Ears National Monument in San Juan County, Utah, United States. The larger and higher North Sixshooter Peak rises to an elevation of 6,379 feet, whereas South Sixshooter Peak rises to 6,154 feet, with approximately 1.5 miles (2.4 km) separation between the two. These buttes tower nearly 1,400 feet above the surrounding terrain, and are historic landmarks visible from State Route 211 between Newspaper Rock and the Needles District of Canyonlands National Park. They are situated 1.5 mile outside the boundary of the park, and four miles northwest of Bridger Jack Butte. Variant names for the peaks include "North Six-Shooter Peak", "South Six-shooter Peak", "Six Shooter Peaks", and "Six-shooter Peak". They are so named because of their resemblance to a pair of revolvers pointing skyward.
Bridger Jack Butte is a sandstone butte located in Bears Ears National Monument, in San Juan County, Utah, United States. Set at the northern tip of Bridger Jack Mesa and above the confluence of Indian and Lavender Creeks, the summit rises to an elevation of 5,890 feet, and towers over 700 feet above the surrounding terrain and floor of Lavender Canyon to its west. This landmark is situated four miles southeast of the Sixshooter Peaks, and is visible from State Route 211 between Newspaper Rock and the Needles District of Canyonlands National Park. "Bridger Jack" was a Paiute medicine man.
