A canyon or gorge is a deep cleft between escarpments or cliffs resulting from the erosive activity of a river over geologic timescales. A canyon may refer to a rift between two peaks, such as those in ranges including the Rocky Mountains, the Alps. Usually a river or stream and erosion carve out such splits between mountains, examples of mountain-type canyons are Provo Canyon in Utah or Yosemite National Park in Californias Sierra Nevada. Canyons within mountains, or gorges that have an opening on one side are called box canyons. Slot canyons are very narrow canyons, often with smooth walls, steep-sided valleys in the seabed of the continental slope underwater are referred to as submarine canyons. Unlike canyons on land, submarine canyons are thought to be formed by turbidity currents, the word canyon is Spanish in origin, with the same meaning. The word canyon is used in North America while the words gorge and ravine are used in Europe and Oceania, though gorge. In the United States, place names generally use canyon in the southwest and gorge in the northeast, in Canada, a gorge is usually narrow while a ravine is more open and often wooded.
The military-derived word defile is occasionally used in the United Kingdom, most canyons were formed by a process of long-time erosion from a plateau or table-land level. The cliffs form because harder rock strata that are resistant to erosion, Canyons are much more common in arid than in wet areas because physical weathering has a more localized effect in arid zones. The wind and water from the combine to erode and cut away less resistant materials such as shales. The freezing and expansion of water serves to help form canyons, water seeps into cracks between the rocks and freezes, pushing the rocks apart and eventually causing large chunks to break off the canyon walls, in a process known as frost wedging. Canyon walls are formed of resistant sandstones or granite. Sometimes large rivers run through canyons as the result of geological uplift. These are called entrenched rivers, because they are unable to alter their course. In the United States, the Colorado River in the Southwest, Canyons often form in areas of limestone rock.
As limestone is soluble to an extent, cave systems form in the rock. When these collapse, a canyon is left, as in the Mendip Hills in Somerset and Yorkshire Dales in Yorkshire, England
United States Forest Service
The United States Forest Service is an agency of the U. S. Department of Agriculture that administers the nations 154 national forests and 20 national grasslands, which encompass 193 million acres. Major divisions of the include the National Forest System and Private Forestry, Business Operations. Managing approximately 25% of federal lands, it is the major national land agency that is outside the U. S. Department of the Interior. The concept of the National Forests was born from Theodore Roosevelt’s conservation group and Crockett Club, in 1876, Congress created the office of Special Agent in the Department of Agriculture to assess the quality and conditions of forests in the United States. Hough was appointed the head of the office, in 1881, the office was expanded into the newly formed Division of Forestry. The Forest Reserve Act of 1891 authorized withdrawing land from the domain as forest reserves. In 1901, the Division of Forestry was renamed the Bureau of Forestry, gifford Pinchot was the first United States Chief Forester in the Presidency of Theodore Roosevelt.
As of 2009, the Forest Service has a budget authority of $5.5 billion. The Forest Service employs 34,250 employees in 750 locations, including 10,050 firefighters,737 law enforcement personnel, and 500 scientists. The mission of the Forest Service is To sustain the health and its motto is Caring for the land and serving people. As the lead agency in natural resource conservation, the US Forest Service provides leadership in the protection and use of the nations forest, rangeland. The agencys ecosystem approach to management integrates ecological and social factors to maintain and enhance the quality of the environment to meet current, the everyday work of the Forest Service balances resource extraction, resource protection, and providing recreation.5 billion trees per year. Further, the Forest Service fought fires on 2,996,000 acres of land in 2007, the Forest Service organization includes ranger districts, national forests, research stations and research work units and the Northeastern Area Office for State and Private Forestry.
Each level has responsibility for a variety of functions, the Chief of the Forest Service is a career federal employee who oversees the entire agency. The Chief reports to the Under Secretary for Natural Resources and Environment in the U. S. Department of Agriculture, there are five deputy chiefs for the following areas, National Forest System and Private Forestry and Development, Business Operations, and Finance. The Forest Service Research and Development deputy area includes five stations, the Forest Products Laboratory. Station directors, like regional foresters, report to the Chief, Research stations include Northern, Pacific Northwest, Pacific Southwest, Rocky Mountain, and Southern. There are 92 research work units located at 67 sites throughout the United States, there are 80 Experimental Forests and Ranges that have been established progressively since 1908, many sites are more than 50 years old
Cumberland Gap National Historical Park
Established on June 11,1940, Cumberland Gap National Historical Park is a United States National Historical Park located at the border between Kentucky and Virginia. The Cumberland Gap is a natural break in the Appalachian Mountains. The park lies in parts of Bell and Harlan counties in Kentucky, Claiborne County in Tennessee, the park contains the Kentucky-Virginia-Tennessee tri-state area, accessible via a short trail. Cumberland Gap National Historical Park covers 20,508 acres, the Cumberland Gap Visitor Center is located on U. S. Highway 25E just southeast of Middlesboro and just northwest of the Cumberland Gap Tunnel and Cumberland Gap, Tennessee. The visitor center is open day of the year except Christmas Day. The gap was used by Native Americans, as many species of migratory animals passed through it from north to south each year. It was fertile hunting territory and the only cut through the mountains from the southern wintering grounds of wild deer. Starting around 1775, the Gap became the route of transit for American settlers moving west into Kentucky.
Two families by the name of Hensley and Gibbons moved to Brush Mountain to escape the many changes that were taking place in the early 1900s, more family members followed and a community was begun. A church and school was established under the jurisdiction of the Bell County School System of Bell County, settlers continued their pioneer lifestyle until future generations began accepting employment and marriage partners off the mountain. Sherman Hensley, the founder of the settlement, was the last to leave in 1951, the park preserves the natural beauty of the surrounding area while focusing on historic preservation. The former roadbed of U. S. Highway 25E through the park has been restored to an early 19th-century wagon path and this was made possible with the 1996 completion of the Cumberland Gap Tunnel, which rerouted US 25E under the park
Mammoth Cave National Park
Mammoth Cave National Park is a U. S. national park in central Kentucky, encompassing portions of Mammoth Cave, the longest cave system known in the world. Since the 1972 unification of Mammoth Cave with the system under Flint Ridge to the north. The park was established as a park on July 1,1941. It became a World Heritage Site on October 27,1981, the parks 52,830 acres are located primarily in Edmonson County, with small areas extending eastward into Hart County and Barren County. It is centered on the Green River, with a tributary, with 405 miles of surveyed passageways Mammoth Cave is by far the worlds longest known cave system, being over twice as long as the second-longest cave system, Mexicos Sac Actun underwater cave. Mammoth Cave developed in thick Mississippian-aged limestone strata capped by a layer of sandstone and it is known to include more than 390 miles of passageway, new discoveries and connections add several miles to this figure each year. Mammoth Cave National Park was established to preserve the cave system, the epikarstic zone concentrates local flows of runoff into high-elevation springs which emerge at the edges of ridges.
It is in underlying massive limestone layers that the human-explorable caves of the region have naturally developed. The limestone layers of the column beneath the Big Clifty, in increasing order of depth below the ridgetops, are the Girkin Formation. Genevieve Limestone, and the St. Louis Limestone, for example, the large Main Cave passage seen on the Historic Tour is located at the bottom of the Girkin and the top of the Ste. Each of the layers of limestone is divided further into named geological units and subunits. One area of research involves correlating the stratigraphy with the cave survey produced by explorers. This makes it possible to produce approximate three-dimensional maps of the contours of the layer boundaries without the necessity for test wells. The upper sandstone caprock is relatively hard for water to penetrate, the sandstone caprock layer has been dissolved and eroded at many locations within the park, such as the Frozen Niagara room. At one valley bottom in the region of the park.
Known as Cedar Sink, the features a small river entering one side. Mammoth Cave is home to the endangered Kentucky cave shrimp, a sightless albino shrimp, the National Park Service offers several cave tours to visitors. Some notable features of the cave, such as Grand Avenue, Frozen Niagara, two tours, lit only by visitor-carried paraffin lamps, are popular alternatives to the electric-lit routes
Sandstone is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz or feldspar because these are the most common minerals in the Earths crust, like sand, sandstone may be any color, but the most common colors are tan, yellow, grey, pink and black. Since sandstone beds often form highly visible cliffs and other topographic features, quartz-bearing sandstone is converted into quartzite through heating and pressure, usually related to tectonic compression within orogenic belts. They are formed from cemented grains that may either be fragments of a rock or be mono-minerallic crystals. The cements binding these grains together are typically calcite, grain sizes in sands are defined within the range of 0.0625 mm to 2 mm. The formation of sandstone involves two principal stages, first, a layer or layers of sand accumulates as the result of sedimentation, either from water or from air. Typically, sedimentation occurs by the settling out from suspension.
The most common cementing materials are silica and calcium carbonate, which are derived either from dissolution or from alteration of the sand after it was buried. Colours will usually be tan or yellow, a predominant additional colourant in the southwestern United States is iron oxide, which imparts reddish tints ranging from pink to dark red, with additional manganese imparting a purplish hue. Red sandstones are seen in the Southwest and West of Britain, as well as central Europe. The regularity of the latter favours use as a source for masonry, either as a building material or as a facing stone. These physical properties allow the grains to survive multiple recycling events. Quartz grains evolve from rock, which are felsic in origin. Feldspathic framework grains are commonly the second most abundant mineral in sandstones, Feldspar can be divided into two smaller subdivisions, alkali feldspars and plagioclase feldspars. The different types of feldspar can be distinguished under a petrographic microscope, below is a description of the different types of feldspar.
Alkali feldspar is a group of minerals in which the composition of the mineral can range from KAlSi3O8 to NaAlSi3O8. Plagioclase feldspar is a group of solid solution minerals that range in composition from NaAlSi3O8 to CaAl2Si2O8. Lithic framework grains are pieces of ancient source rock that have yet to weather away to individual mineral grains, accessory minerals are all other mineral grains in a sandstone, commonly these minerals make up just a small percentage of the grains in a sandstone
Carter Caves State Resort Park
Carter Caves State Resort Park is located in Carter County, United States, along Tygarts Creek. It is formed by Carter Caves, and nearby Cascade Caves, on December 16,1981,146 acres of the park were designated as nature preserves. Bat Cave and Cascade Caverns State Nature Preserves were dedicated for the protection of the Indiana bat, mountain maple, the purchase of the caves and surrounding land was driven by Governor William Jason Fields, a native of Carter County. Carter Caves is a resort park that features a lodge, cottages, 18-hole putt-putt course, 9-hole golf course, full-service campground. It has various tours available year-round that displays and explains the wonders of the underground world. It has horse riding stables. It is well known for its splendor above and below ground, there are several different Cave Tours offered. Guided tours of Cascade Cave and X-Cave are available year-round, Cascade Cave is the name for three different caves in the same area and is together the largest cave in the park.
It features an underground room and an 30-foot underground waterfall. X Cave, named for the pattern of its passages, features some of the largest rock formations in the park. Saltpetre Cave was mined during the War of 1812 because saltpetre, historic activities are a major part of the Saltpetre Cave tour. Bat Cave is toured in the months, between Memorial Day and Labor Day, and is considered a wild cave tour since the cave has not been improved for walking tours. The cave is unique in that it is a hibernaculum for the endangered Indiana Bat in the winter months, Laurel Cave is the most visited of the non-commercial caves in the park, and contains some of the most interesting passages. Laurel Cave is open to the public during business hours in the summer months only. All that is required is a permit available at the Welcome Center/Gift Shop, the permit gives you legal access to Laurel Cave, Horn Hollow Caves and the connected Rimstone Cave. Over thirty miles of hiking trails encounter seven natural bridges throughout the park, the Cascade Trail is a three-quarter mile trail passing through Box Canyon.
The Three Bridges Trail winds three and a quarter miles and includes the parks largest natural bridge, the Smokey Bridge and this trail passes by Fern Bridge and Raven Bridge as it meanders through the park. The half-mile Natural Bridge Trail passes beneath a natural bridge

Blue Licks Battlefield State Resort Park
Blue Licks Battlefield State Resort Park is a park located near Mount Olivet, Kentucky in Robertson and Nicholas counties. The park encompasses 148 acres and features a monument commemorating the August 19,1782 Battle of Blue Licks, the battle was regarded as the final battle of the American Revolutionary War. The earliest accounts of Blue Licks describe it as a place where animals gathered to lick the salt deposits flowing from the springs in the area. The Reverend James Smith provides this account in his 1795–97 diary, As you approach the Licks, at the distance of 4 or 5 miles from it, you begin to perceive the change. Here immense herds of buffalo used formerly to meet and with their fighting, scraping etc. have worn away the ground to what it is at present, in 1782, British Captain William Caldwell led a force of Indians against the small Kentucky settlement of Bryans Station. Caldwell met stiff resistance, and after two days, retreated toward the Ohio River, in the battle that followed,60 of the 176 men who followed McGary were killed, Boones son Israel among them.
Reinforcements under George Rogers Clark eventually arrived and drove Caldwells forces from Kentucky for good, by the mid-19th century, the Blue Licks area had become a health resort, due in large part to the nearby saltwater springs that had been used for salt making since the 1770s. The mineral water found in the springs was rumored to cure everything from asthma to gout, by 1896, the areas last spring had gone dry. Efforts to locate another spring unearthed several geological and historical artifacts, a more extensive excavation of the area was conducted in 1945. However, a team from Morehead State University is to search the battlefield using modern equipment to explore for artifacts relating to the battlefields, enough success in this endeavor could mean the return of the battlefield to the Register. The park is located along the Licking River, and offers canoeing and fishing, the Licking River Trail offers a one-mile hike along the riverbank. Overnight stays are accommodated at the 32-room lodge or the 51-site campground, the park features a 15-acre nature preserve containing a cedar glade.
This glade was previously maintained as an area by the large numbers of herbivores, such as bison, elk. Today much of the glade has transitioned into forest, but the remnant areas are being maintained by controlled burns and these remnants are home to the federally endangered Shorts goldenrod and the state threatened Great Plains Ladies-tresses. The Pioneer Museum is the major attraction. It houses a variety of artifacts, from a tooth found during an excavation of the site to relics from the American Civil War. Exhibits focus on the natural and cultural history, including prehistoric animals and fossils, area Native Americans and 18th century pioneers. The museum was dedicated in 1931, saw renovations completed in 2007, the Battle of Blue Licks celebration is held annually in mid-August and features a re-enactment of the Battle of Blue Licks
Daniel Boone National Forest
Daniel Boone National Forest is the only national forest completely within the boundary of Kentucky. Established in 1937, it was named the Cumberland National Forest. The forest was named after Daniel Boone, a frontiersman and explorer in the late 18th century who contributed greatly to the exploration, in 1937, a national forest was established containing 1,338,214 acres within its proclamation boundary. As of June 1937, the Forest Service had purchased only 336,692 acres, most early purchases were large, isolated tracts owned by lumber and coal companies with but few inhabitants. The Forest Service has since had difficulty acquiring more land within the boundary, the bulk of which was. Due in part to World War II, funds for land acquisition were curtailed in the early 1940s, substantial acquisition efforts could not resume until the mid-1960s. The lengthy cessation of land acquisitions, except for period during the forests renaming, naming the forest entailed considerable debate. Protests began immediately after the national forest was named, the naming issue was reopened in the late 1950s.
The Forest Service investigated the name Cumberland, and found it came to Kentucky in 1750 when Thomas Walker named the Cumberland River in honor of Prince William Augustus, the Duke had defeated the Scottish Highlanders in 1746 at the Battle of Culloden, an especially brutal conflict. Many Scottish families fled to America and ultimately Kentucky as a result of the event, the Forest Service found that for their descendants still living in Eastern Kentucky, the name Cumberland was particularly distasteful. In addition, the Forest Service noted the influence of history on the names of places in Kentucky, during this period of time, place names with British connotations fell out of favor and changes were made. For example, prior to the Revolution, the Kentucky River was called the Louisa River, after the wife of the Duke of Cumberland, during the 1960s, a new movement to rename the national forest took place. Also during the 1960s, part of the national forest was designated a Primitive Weapons Area and set apart for hunting with longbow, crossbow, in 1970, this was the only US area where deer could legally be hunted with crossbows.
The park remains unique still for allowing only muzzle-loaded firearms, in 1967, a large and disconnected addition to the national forest was created, called the Redbird Purchase Unit, after a key purchase from the Red Bird Timber Company. About a third of the land within the national forest proclamation boundary is owned or managed by the Forest Service, the pattern of land ownership is highly fragmented and changes relatively frequently. One of the goals of the Forest Service is to consolidate holdings into larger blocks, the boundaries of Forest Service lands are marked in various ways, including red paint on trees. The shifting boundaries and growing size of Forest Service lands sometimes results in local complaints, in addition, it can be difficult for recreational users to know whether they are on Forest Service lands or not. No Trespassing signs are used by landowners, and conflicts between landowners and recreational users are not uncommon
George Washington and Jefferson National Forests
The George Washington and Jefferson National Forests are U. S. National Forests that combine to form one of the largest areas of public land in the Eastern United States. They cover 1.8 million acres of land in the Appalachian Mountains of Virginia, West Virginia, approximately 1 million acres of the forest are remote and undeveloped and 139,461 acres have been designated as wilderness areas, which eliminates future development. George Washington National Forest was established on May 16,1918 as the Shenandoah National Forest, the forest was renamed after the first President on June 28,1932. Natural Bridge National Forest was added on July 22,1933, Jefferson National Forest was formed on April 21,1936 by combining portions of the Unaka and George Washington National Forests with other land. In 1995, the George Washington and Jefferson National Forests were administratively combined, the border between the two forests roughly follows the James River. The combined forest is administered from its headquarters in Roanoke, the northern portion of the Blue Ridge Parkway, which is separately administered by the National Park Service, runs through the Forest.
Over 2,000 miles of hiking trails, including segments of the Appalachian Trail, virginias highest point, Mount Rogers, is located in the Mount Rogers National Recreation Area that is part of the forest. Other notable mountains include Elliott Knob, which has one of the last remaining fire towers in the eastern U. S. Approximately 230,000 acres of old-growth forests, the deepest gorge east of the Mississippi River, Breaks Interstate Park, is located in the forest. Roaring Run Furnace is the site on the National Register of Historic Places owned by the Jefferson National Forest. The Forests vast and mountainous terrain harbors a variety of plant life—over 50 species of trees and over 2,000 species of shrubs. The Forests contain some 230,000 acres of old growth forests, the Ramseys Draft and Kimberling Creek Wildernesses in particular are mostly old-growth. The black bear is relatively common, enough so there is a short hunting season to prevent overpopulation. White-tailed deer, bald eagles, otter, the forests are popular hiking, mountain biking, and hunting destinations.
The Appalachian Trail extends for 330 miles from the end of Shenandoah National Park through the forest. The forest is within a two-hour drive for over ten people and thus receives large numbers of visitors. The George Washington National Forest is a destination for trail runners. It is the location for several Ultramarathons, including the Massanutten Mountain Trails 100 miler, the Old Dominion 100 miler, George Washington Forest is the venue for Nature Camp, a natural science education-oriented summer camp for youth
