Cathedral Rock
Cathedral Rock is a natural sandstone butte on the Sedona, Arizona, Sedona skyline and one of the most-photographed sights in Arizona, United States. The rock formation is located in the Coconino National Forest in Yavapai County, Arizona, Yavapai County, about a mile (1.6 km) west of Arizona State Route 179, Arizona Route 179, and about south of the "Y" intersection of Routes 179 and 89A in uptown Sedona. The summit elevation of Cathedral Rock is . The Cathedral Rock trail (USFS Trail #170) is a popular short, steep ascent from the Back O' Beyond trailhead to the saddle points or "gaps" in Cathedral Rock. Geologically, Cathedral Rock is carved from the Permian Schnebly Hill formation, a redbed sandstone formed from coastal sand dunes near the shoreline of the ancient Pedregosa Sea. Ripple marks are prominent along the lower Cathedral Rock trail, and a black basalt dike (geology), dike may be seen in the first saddle. Cathedral Rock was called "Court House Rock" on some ...

Buttes Of Arizona
__NOTOC__ In geomorphology, a butte () is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller landforms than mesas, plateaus, and tablelands. The word ''butte'' comes from a French word meaning knoll (but of any size); its use is prevalent in the Western United States, including the southwest where ''mesa'' (Spanish for "table") is used for the larger landform. Due to their distinctive shapes, buttes are frequently landmarks in plains and mountainous areas. To differentiate the two landforms, geographers use the rule of thumb that a mesa has a top that is wider than its height, while a butte has a top that is narrower than its height. Formation Buttes form by weathering and erosion when hard caprock overlies a layer of less resistant rock that is eventually worn away. The harder rock on top of the butte resists erosion. The caprock provides protection for the less resistant rock below from wind abrasion which leaves it standin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell Rock (Arizona)
Bell Rock is a butte just north of the Village of Oak Creek, Arizona, south of Sedona in Yavapai County. With an elevation at its summit of , it is just west of Courthouse Butte. Its panoramic views make it a popular landmark and tourist attraction. The most popular route is a moderate hike that reaches a small plateau on the northwest face of the butte. A challenging unmarked trail must be taken to reach the summit. Geology Bell Rock is a butte composed of horizontally bedded sedimentary rock of the Permian Supai Formation.

Red Rock State Park
Red Rock State Park is a state park of Arizona, United States, featuring a red sandstone canyon outside the city of Sedona, Arizona, Sedona. The main mission of this day-use park is the preservation of the riparian habitat along Oak Creek. Red Rock State Park serves as an environmental education facility for the public and for school or private groups, and provides limited passive recreational opportunities. Natural history Red Rock State Park includes a stretch of Oak Creek, which upstream flows through the famous Oak Creek Canyon in Coconino National Forest. The rich riparian zone along the creek supports a diverse array of species. Trees in this habitat include Populus fremontii, Fremont cottonwood, Platanus wrightii, Arizona sycamore, Fraxinus velutina, velvet ash, and Alnus oblongifolia, Arizona alder. Oak Creek supports rare native fish, several frog species, and the threatened species, threatened Sonora mud turtle. Away from the creek the dominant trees are Prosopis ...

Red Rock Crossing
Red Rock is a place in Yavapai County, Arizona, United States. Red Rock is southwest of Sedona. Red Rock Crossing is a former ford across Oak Creek with views of Cathedral Rock. The crossing was washed out in a flood in 1978, and there are no current plans to reopen it to automobile traffic. Most of the crossing is included in the Coconino National Forest's Crescent Moon Ranch recreation area. Baldwins Crossing is an alternate name for the ford.

Dike (geology)
A dike or dyke, in Geology, geological usage, is a sheet of rock that is formed in a Fracture (geology), fracture of a pre-existing rock body. Dikes can be either Intrusive rock, magmatic or Sedimentary rock, sedimentary in origin. Magmatic dikes form when magma flows into a crack then solidifies as a sheet intrusion, either cutting across layers of rock or through a contiguous mass of rock. Clastic dikes are formed when sediment fills a pre-existing crack.Essentials of Geology, 3rd Ed, Stephen Marshak Magmatic dikes A magmatic dike is a sheet of igneous rock that cuts across older rock beds. It is formed when magma fills a fracture in the older beds and then cools and solidifies. The dike rock is usually more resistant to weathering than the surrounding rock, so that erosion exposes the dike as a natural wall or ridge. It is from these natural walls that dikes get their name. Dikes preserve a record of the fissures through which most mafic magma (fluid magma low in silica) reac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Ripple Marks
In geology, ripple marks are sedimentary structures (i.e., bedforms of the lower flow regime) and indicate agitation by water (current or waves) or wind. Defining ripple cross-laminae and asymmetric ripples * ''Current ripple marks'', ''unidirectional ripples'', or ''asymmetrical ripple marks'' are asymmetrical in profile, with a gentle up-current slope and a steeper down-current slope. The down-current slope is the angle of repose, which depends on the shape of the sediment. These commonly form in fluvial and aeolian depositional environments, and are a signifier of the lower part of the Lower Flow Regime. * Ripple cross-laminae forms when deposition takes place during migration of current or wave ripples. A series of cross-laminae are produced by superimposing migrating ripples. The ripples form lateral to one another, such that the crests of vertically succeeding laminae are out of phase and appear to be advancing upslope. This process results in cross-bedded units t ...

Sand Dunes
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented san ...
