Castle Rock is a 6,340-foot-elevation (1,932-meter) summit in San Juan County, Utah, United States. [2]
Castle Rock is situated four miles (6.4 km) north-northeast of the Monument Valley Tribal Park Visitor Center, on Navajo Nation land. It is an iconic landform of Monument Valley and can be seen from Highway 163. Precipitation runoff from this landform's slopes drains into the San Juan River drainage basin. [3] Topographic relief is significant as the summit rises 800 feet (244 meters) above the surrounding terrain in 0.25 mile (0.4 km). This landform's toponym has been officially adopted by the United States Board on Geographic Names. [2] It is so named because the butte resembles the silhouette of a castle. [4] The first ascent of the summit was made on May 8, 1960, by Harvey T. Carter, Layton Kor, and John Auld. [5] [6]
Castle Rock is composed of three principal strata. The bottom layer is slope-forming Organ Rock Shale, the next stratum is cliff-forming De Chelly Sandstone, and the upper layer is Moenkopi Formation. The rock ranges in age from Permian at the bottom to Triassic at the top. The buttes and mesas of Monument Valley are the result of the Organ Rock Shale being more easily eroded than the overlaying sandstone. [7]
Spring and fall are the most favorable seasons to visit Castle Rock. According to the Köppen climate classification system, it is located in a semi-arid climate zone with cold winters and hot summers. Summers average 54 days above 90 °F (32 °C) annually, and 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. [8]
Monument Valley is a region of the Colorado Plateau characterized by a cluster of sandstone buttes, with the largest reaching 1,000 ft (300 m) above the valley floor. The most famous butte formations are located in northeastern Arizona along the Utah–Arizona state line. The valley is considered sacred by the Navajo Nation, the Native American people within whose reservation it lies.
Steve Roper is a noted climber and historian of the Sierra Nevada in the United States. He along with Allen Steck are the founding editors of the Sierra Club journal Ascent.
Layton Kor was an American rock climber active in the 1960s, whose first ascents and drive for climbing are well known in the climbing world. His routes included many climbs in Eldorado Canyon, near Boulder, Colorado, The Diamond on Longs Peak, towers in the desert southwest, and Yosemite National Park, among other locations. Notable among his first ascents is the Kor-Ingalls Route on Castleton Tower and The Finger of Fate Route up the Fisher Towers' Titan; both routes are recognized in the historic climbing text Fifty Classic Climbs of North America.
Castleton Tower is a 6,660-foot (2,030 m) summit on the northeastern border of Castle Valley, Utah. The Wingate Sandstone tower itself is 400 feet (120 m) high and stands on a 1,000-foot (300 m) Moenkopi-Chinle cone. Castleton Tower is world-renowned as a subject for photography and for its classic rock climbing routes, the most famous of which is the Kor-Ingalls Route featured in Fifty Classic Climbs of North America. It can be accessed by a trail that begins south of the tower at a primitive camp ground.
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".
Kissing Couple is a 5,815-foot-elevation (1,772-meter) sandstone pillar located in Colorado National Monument, in Mesa County of western Colorado, United States. This iconic 400-foot-high tower is situated on the west side of Monument Canyon, 1.5 mile southeast of the monument's visitor center, and nine miles (14 km) west of the community of Grand Junction. It is also a half-mile south-southeast of another popular climbing destination, Independence Monument, and both can be seen from viewpoints along Rim Rock Drive. It is so named because it resembles an embracing couple. This geographical feature's name was officially adopted in 1982 by the United States Board on Geographic Names. Older USGS maps have the feature's name misplaced by about one-half mile to the southeast. The first ascent of the summit was made May 4, 1960, by Layton Kor, Harvey Carter, and John Auld via the five pitch, class 5.11a route named Long Dong Wall. The first free ascent was made in 1977 by Andy Petefish, Tom Stubbs, and Jim Pearson. Some climbers alternatively refer to Kissing Couple as "Bell Tower."
Sentinel Mesa is a 6,450-foot-elevation (1,966-meter) summit in San Juan County, Utah, United States. It is situated 1.5 miles (2.4 km) north of the Monument Valley visitor center on Navajo Nation land and can be seen from Highway 163. The mesa is immediately northwest of the iconic West and East Mitten Buttes. The nearest higher neighbor is Brighams Tomb, 2.64 miles (4.25 km) to the north-northeast. Precipitation runoff from this mesa's west slope drains to Mitchell Butte Wash, whereas the east slope drains to West Gypsum Creek, which are both part of the San Juan River drainage basin. The "Sentinel" name refers to how the mesa oversees Monument Valley which the Navajo consider as one of the "door posts" to Monument Valley. The landform's toponym has been officially adopted by the U.S. Board on Geographic Names.
