Spearhead Mesa
Spearhead Mesa is a summit in Navajo County, Arizona, United States. Description Spearhead Mesa is situated southeast of the Monument Valley visitor center on Navajo Nation land. The nearest higher neighbor is the iconic East Mitten Butte, to the north-northwest. Precipitation runoff from this mesa's slopes drains into Gypsum Creek which is a tributary of the San Juan River. Topographic relief is significant as the summit rises above the surrounding terrain in one-quarter mile (0.4 km). The landform's toponym has been officially adopted by the U.S. Board on Geographic Names. The spearhead name refers to a sandstone spire above Artist Point that resembles the spear of an arrow. Geology Spearhead Mesa is a mesa 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 with a Shinarump Conglomerate caprock.

Totem Pole (Monument Valley)
The Totem Pole is a pillar or rock spire found in Monument Valley. It is a highly eroded remnant of a butte. Deserts at the end of the Permian period, 260 million years ago, formed the De Chelly and Wingate Sandstones that make up the buttes, totems, and mesas in Monument Valley. The Totem Pole rises next to a gathering of thicker spires the Navajo called Yei Bi Chei and can be seen via a self-guided Valley Drive. Rock climbing The Totem Pole was first climbed June 11–13, 1957 by Bill Feuerer, Jerry Gallwas, Mark Powell and Don Wilson. The first ascent route is rated 5.10 YDS A2 in the Yosemite Decimal System. A second route called "Never Never Land" was climbed in 1979. Parts of the 1975 thriller film ''The Eiger Sanction'' (U.S. director Clint Eastwood) were filmed at Totem Pole. According to author Ron Hogan, " addition to directing and starring in The Eiger Sanction, Clint Eastwood did all his own stunts during the mountain-climbing sequences." Hogan further adds tha ...

Diurnal Temperature Variation
In meteorology, diurnal temperature variation is the variation between a high air temperature and a low temperature that occurs during the same day. Temperature lag Temperature lag, also known as thermal inertia, is an important factor in diurnal temperature variation. Peak daily temperature generally occurs ''after'' noon, as air keeps absorbing net heat for a period of time from morning through noon and some time thereafter. Similarly, minimum daily temperature generally occurs substantially after midnight, indeed occurring during early morning in the hour around dawn, since heat is lost all night long. The analogous annual phenomenon is seasonal lag. As solar energy strikes the Earth's surface each morning, a shallow layer of air directly above the ground is heated by conduction. Heat exchange between this shallow layer of warm air and the cooler air above is very inefficient. On a warm summer's day, for example, air temperatures may vary by from just above the ground t ...

Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSh'' and ''BSk'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as they usually cannot support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): * ...

Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...
