The Palisades Sill is a fine-grained porphyritic dacite sill which forms spectacular cliffs and palisades in the Cimarron River canyon between Eagle Nest and Cimarron in northern New Mexico. It can be seen in the eastern part of Cimarron Canyon State Park. [1]
Porphyritic is an adjective used in geology, specifically for igneous rocks, for a rock that has a distinct difference in the size of the crystals, with at least one group of crystals obviously larger than another group. Porphyritic rocks may be aphanites or extrusive rock, with large crystals or phenocrysts floating in a fine-grained groundmass of non-visible crystals, as in a porphyritic basalt, or phanerites or intrusive rock, with individual crystals of the groundmass easily distinguished with the eye, but one group of crystals clearly much bigger than the rest, as in a porphyritic granite. Most types of igneous rocks may display some degree of porphyritic texture. One main type of rock that has a porphyritic texture are porphyry, though not all porphyritic rocks are porphyries.
Dacite is an igneous, volcanic rock. It has an aphanitic to porphyritic texture and is intermediate in composition between andesite and rhyolite. The word dacite comes from Dacia, a province of the Roman Empire which lay between the Danube River and Carpathian Mountains where the rock was first described.
In geology, a sill is a tabular sheet intrusion that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or along the direction of foliation in metamorphic rock. A sill is a concordant intrusive sheet, meaning that a sill does not cut across preexisting rock beds. Stacking of sills builds a sill complex and a large magma chamber at high magma flux. In contrast, a dike is a discordant intrusive sheet, which does cut across older rocks. Sills are fed by dikes, except in unusual locations where they form in nearly vertical beds attached directly to a magma source. The rocks must be brittle and fracture to create the planes along which the magma intrudes the parent rock bodies, whether this occurs along preexisting planes between sedimentary or volcanic beds or weakened planes related to foliation in metamorphic rock. These planes or weakened areas allow the intrusion of a thin sheet-like body of magma paralleling the existing bedding planes, concordant fracture zone, or foliations.

Mount Sill is one of the fourteeners of the Sierra Nevada in California. It is located in the Palisades, a group of striking rock peaks with a few small glaciers on their flanks. Mount Sill is located 0.6 miles (1 km) east of North Palisade, the high point of the group. The two peaks are connected by a high, rocky ridge, on the north side of which lies the Palisade Glacier. Mount Sill lies on the main Sierra Crest, but is at a point where the crest turns sharply, giving it particularly striking summit views. On one side is Kings Canyon National Park and Fresno County; on the other is the John Muir Wilderness, Inyo National Forest and Inyo County.
Vulture Glacier is located in Banff National Park, Alberta, Canada, northwest of Lake Louise, and can be viewed from the Icefields Parkway. Vulture Glacier is an outflow glacier from the Wapta Icefield, which rests along the Continental Divide. The glacier had an area of 4.9 km² (1.9 mi²) in the 1980s, however, all of the glaciers in the Canadian Rockies have been retreating steadily since the middle of the 19th century.
The Chuska Mountains are an elongate range on the southeast Colorado Plateau and within the Navajo Nation whose highest elevations approach 10,000 feet. The range is about 80 by 15 km. It trends north-northwest and is crossed by the state line between Arizona and New Mexico. The highlands are a dissected plateau, with an average elevation of about 2,740 m (8,990 ft), and subdued topography. The highest point is Roof Butte at 2,994 m (9,823 ft), near the northern end of the range in Arizona. Other high points include the satellite Beautiful Mountain at 2,861 m (9,386 ft) and Lukachukai Mountains at 2,885 m (9,465 ft), both also near the northern end, and Matthews Peak at 2,911 m (9,551 ft). The San Juan Basin borders the Chuskas on the east, and typical elevations in nearby parts of that basin are near 1,800 m (5,900 ft). The eastern escarpment of the mountains is marked by slumps and landslides that extend out onto the western margin of the San Juan Basin. To the north, the Chuskas are separated from the Carrizo Mountains by Red Rock Valley, which is today commonly referred to as Red Valley.
The Beamer Trail is a backpacking trail located on the South Rim of the Grand Canyon National Park, located in the U.S. state of Arizona.
The Cimarron River, flowing entirely in New Mexico, was also known as La Flecha or Semarone. Its headwaters are Moreno, Sixmile, and Cieneguilla creeks in the Sangre de Cristo Mountains, which feed into Eagle Nest Dam. From the dam, it runs for 60 miles (97 km) to below the city of Springer, New Mexico in the Taylor Springs area, where it flows into the Canadian River, the southwestern-most major tributary flowing into the Mississippi River via the Arkansas River sub-basin.

The Palisades Sill is a Triassic, 200 Ma diabase intrusion. It extends through portions of New York and New Jersey. It is most noteworthy for The Palisades, the cliffs that rise steeply above the western bank of the Hudson River. The ideal location and accessibility of the sill, as well as its unique features, have generated much attention from nature enthusiasts, rock climbers, and geologists alike.
Northwestern Oklahoma is the geographical region of the state of Oklahoma which includes the Oklahoma Panhandle and a majority of the Cherokee Outlet, stretching to an eastern extent along Interstate 35, and its southern extent along the Canadian River to Noble County. Northwest Oklahoma is also known by its Oklahoma Department of Tourism designation, Red Carpet Country, which is named after the region's red soil and alludes to the metaphor that the panhandle is a "red carpet" into Oklahoma. The region consists of Cimarron, Texas, Beaver, Harper, Woods, Alfalfa, Grant, Kay, Ellis, Woodward, Major, Garfield, Noble, Dewey, Blaine, and Kingfisher counties.

The Hakatai Shale is a Mesoproterozoic rock formation that outcrops in the Grand Canyon, Coconino County, Arizona. It consists of colorful strata that exhibit colors that vary from purple to red to brilliant orange on outcrop. The colors are the result of the oxidation of iron-bearing minerals in the Hakatai Shale. It consists of lower and middle members that consist of bright-red, slope-forming, highly fractured, argillaceous mudstones and shale and an upper member composed of purple and red, cliff-forming, medium-grained sandstone. Its thickness, which apparently increases eastwards, varies form 137 to 300 m. In general, the Hakatai Shale and associated strata of the Unkar Group rocks dip northeast (10°-30°) toward normal faults that dip 60° or more toward the southwest. This can be seen at the Palisades fault in the eastern part of the main Unkar Group outcrop area. In addition, thick, prominent, and dark-colored basaltic sills and dikes cut across the purple to red to brilliant orange strata of the Hakatai Shale.

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
