The Moenkopi Formation is a geological formation that is spread across the U.S. states of New Mexico, northern Arizona, Nevada, southeastern California, eastern Utah and western Colorado. This unit is considered to be a group in Arizona.
A basic stratigraphy of the formation was developed for north-central New Mexico by Wood and Northrop (1946), [3] and stratigraphy in the Four Corners Region was established by the late 1950s. In 1956, Economic geologist Raymond C. Robeck identified and named the Temple Mountain member as the basal-most unit in the area of the San Rafael Swell ...
The Shinarump Conglomerate is a highly resistant coarse-grained sandstone and pebble conglomerate [1] (minor or major conglomerates are a typical base layer after unconformities or disconformities; the Shinarump is a major conglomerate) with rare lenses of mudstone, sometimes forming a caprock because of its hardness, cementation, and erosion resistance.

Milligan Gulch, originally known as La Cañada de la Cruz, or Red Canyon, is a valley in Socorro County New Mexico.Its mouth is its confluence with the Rio Grande at an elevation of 4,459 feet (1,359 meters).
Moenkopi outcrops are found along the Colorado River in Marble Canyon, on Cedar Mountain (a mesa near the southeastern park border), and in Red Butte (located south of Grand Canyon Village). [57] Remnants of the Shinarump Conglomerate , itself a member of the Chinle Formation , are above the Moenkopi Formation near the top of Red Butte but ...

Basins of the Rio Grande Rift Map of physiographic provinces of New Mexico. New Mexico is entirely landbound, with just 0.2% of the state covered with water, [1] and most of the state has an arid to semiarid climate. [2] Much of the state is mountainous, except for the easternmost Great Plains region. [3]

Rincon Valley heads at 33°02′54″N 107°16′41″W / 33.04833°N 107.27806°W / 33.04833; -107.27806 at an elevation of 4,195 feet in a narrow gap between the Caballo Mountains on the east and bluffs on the west bank of the Rio Grande south of where Red ...
