Description

Seven Sailors is situated 15 miles (24 km) west of Bluff, Utah, in the Valley of the Gods, on land administered by the Bureau of Land Management. [3] Precipitation runoff from this landform drains to the San Juan River via Lime Creek. Access to the butte is via the 17-mile Valley of the Gods Road which starts at the intersection with Highway 163 near this butte. Topographic relief is significant as the summit rises 400 feet (122 meters) above the surrounding terrain in 0.1 mile (0.16 km). This landform's descriptive toponym has been officially adopted by the United States Board on Geographic Names. [2]

Geology

Seven Sailors is composed of two principal strata of the Cutler Formation. The bottom layer is slope-forming Halgaito Formation and the upper stratum is cliff-forming Cedar Mesa Sandstone. [4] Cedar Mesa Sandstone is the remains of coastal sand dunes deposited about 270 to 300 million years ago, during the Wolfcampian (early Permian). [5] The buttes of Valley of the Gods are the result of the Halgaito Formation being more easily eroded than the overlaying sandstone. The valley floor is Honaker Trail Formation. [6]

Climate

Spring and fall are the most favorable seasons to visit Seven Sailors. According to the Köppen climate classification system, it is located in a cold semi-arid climate zone with cold winters and hot summers. [7] 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.

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.
