Query: How many state parks are there?
, there were 10,234 state park units in the United States, according to the National Association of State Park Directors (NASPD). There are some 739 million annual visits to the country's state parks. The NASPD further counts over of trail, 217,367 campsites, and 8,277 cabins and lodges across U.S. state parks. The largest state park system in the United States is Alaska State Parks, with over 100 sites encompassing 3.3 million acres.
Many states include designations beyond "state park" in their state parks systems. Other designations might be state recreation areas, state beaches, and state nature reserves. Some state park systems include long-distance trails and historic sites.
Cherry Springs State Park and the surrounding Susquehannock State Forest have recovered from the clearcutting of the lumber era. However, the composition of the forests has changed, so that there are now more hardwoods, including sugar maple and black cherry, and fewer eastern white pine and eastern hemlock. The park also has apple trees from the CCC orchard. Over 400 species of birds have been found in Pennsylvania, including 186 that breed in the state. Birds such as ospreys, hawks, owls, nightjars, and bald eagles have returned to the park and state forest, and saw-whet owls have been studied in the park.
Queensland contains significant areas of rainforest and other areas of biological diversity. World Heritage Areas include the Great Barrier Reef, Wet Tropics of Queensland and Gondwana Rainforests of Australia. Queensland has 226 national parks. The largest is Simpson Desert National Park in the remote central west of the state. The most visited national parks in South East Queensland are Tamborine National Park, Lamington National Park and Noosa National Park. These parks are located near centres of major population and are the most accessible in the state. Lamington and other parks around the Scenic Rim such as Main Range National Park, are included in the World Heritage listed Gondwana Rainforests of Australia.
The Civilian Conservation Corps (CCC) established a camp in 1935 at the present park site. The National Park Service (NPS) which managed the camp, proposed to help Oklahoma to develop a system of state parks, using CCC workers who were already trained in all aspects of park development. The state legislature created the Oklahoma Parks Commission, State Fish and Game Commission, under the auspices of the Oklahoma Fish and Game Commission, to manage the newly created system, and provided funding of $10,000. The City of Altus and private donors bought of land for the park. NPS spent about USD500,000 building roads, trails, rest rooms and other amenities. Quartz Mountain became one of the first seven state parks in Oklahoma when the NPS turned the completed project over to the state in 1937.
The state park was founded in 1922 when the Pennsylvania Department of Forestry established the "Cherry Springs Scenic Drive" on Pennsylvania Route 44. The land where the hotel was and which became Cherry Springs State Park was purchased by the state in 1932. On May 27, 1933, Civilian Conservation Corps (CCC) Camp S-136-Pa was established at Cherry Springs and built many of the park facilities. CCC Camp S-88-Pa, based at nearby Lyman Run in Potter County, also built some facilities in the park.
Tennessee's major industries include agriculture, manufacturing, and tourism. Poultry, soybeans, and cattle are the state's primary agricultural products, and major manufacturing exports include chemicals, transportation equipment, and electrical equipment. The Great Smoky Mountains National Park, the nation's most visited national park, is headquartered in the eastern part of the state, and a section of the Appalachian Trail roughly follows the Tennessee-North Carolina border. Other major tourist attractions include the Tennessee Aquarium in Chattanooga; Dollywood in Pigeon Forge; Ripley's Aquarium of the Smokies and Ober Gatlinburg in Gatlinburg; the Parthenon, the Country Music Hall of Fame and Museum, and Ryman Auditorium in Nashville; the Jack Daniel's Distillery in Lynchburg; Elvis Presley's Graceland residence and tomb, the Memphis Zoo, the National Civil Rights Museum in Memphis; and Bristol Motor Speedway in Bristol.
Navajo County offers not only the Monument Valley, but Keams Canyon, part of the Petrified Forest National Park, and one of the largest contiguous ponderosa pine forest in North America. Navajo County has of federally designated Indian reservation within its borders, the third most of any county in the United States (neighboring Apache County and Coconino County are first and second). In descending order of territory within the county, the reservations are the Navajo Nation, Hopi Indian Reservation, and Fort Apache Indian Reservation, all of which are partly located within Navajo County.As of the 2000 census, there were 97,470 people, 30,043 households, and 23,073 families residing in the county. The population density was 10 people per square mile (4/km²). There were 47,413 housing units at an average density of 5 per square mile (2/km²). The racial makeup of the county was 47.74% Native American, 45.91% White, 0.88% Black or African American, 0.33% Asian, 0.05% Pacific Islander, 3.15% from other races, and 55.94% from two or more races. 8.22% of the population were Hispanic or Latino of any race. 24.77% reported speaking Navajo at home, 5.94% other Southern Athabaskan languages, 4.71% Spanish, and 3.23% Hopi.
The largest national park in the world is the Northeast Greenland National Park, which was established in 1974 and currently protects
The St. Croix river valley was inhabited by Dakota and Ojibwe tribes. European trappers commercialized the fur-trade in the 17th century. Extensive logging took place in the mid-19th century; white pines were the target and most other tree species were ignored. Once the white pine was gone the lumber companies were happy to sell, and a lumber baron named William O'Brien bought up much of the land for his personal estate. In 1945, 20 years after William O'Brien's death, his daughter Alice offered along the riverfront to the state. The donation was eagerly accepted, as Minnesota did not yet have a state park near the Twin Cities, and the park was ratified by the legislature two years later. The proximity to the metro area was a mixed blessing. Land was added to the park at every opportunity, to reduce crowding and to prevent housing developments from being built right up to the boundary. In 1958‚ S. David Greenberg donated Greenberg Island in memory of his parents. Accessible only by canoe‚ the island has become a haven for wildlife and wildflowers. The park was expanded into the bluffs west of Highway 95 and a second campground added. A large tract was added in 1973, leapfrogging a rail line, and another came in 1986. William O'Brien remains one of the top five most-visited state parks in Minnesota.
The Four Corners is a region of the United States consisting of the southwestern corner of Colorado, southeastern corner of Utah, northeastern corner of Arizona, and northwestern corner of New Mexico. The Four Corners area is named after the quadripoint at the intersection of approximately 37° north latitude with 109° 03' west longitude, where the boundaries of the four states meet, and are marked by the Four Corners Monument. It is the only location in the United States where four states meet. Most of the Four Corners region belongs to semi-autonomous Native American nations, the largest of which is the Navajo Nation, followed by Hopi, Ute, and Zuni tribal reserves and nations. The Four Corners region is part of a larger region known as the Colorado Plateau and is mostly rural, rugged, and arid. In addition to the monument, commonly visited areas within Four Corners include Monument Valley, Mesa Verde National Park, Chaco Canyon, Canyons of the Ancients National Monument and Canyon de Chelly National Monument. The most populous city in the Four Corners region is Farmington, New Mexico, followed by Durango, Colorado.
There are 23 league across the United States, in 22 states: Alabama, Arizona, Arkansas, California (NorCal & SoCal), Colorado, Georgia, Idaho, Minnesota, Nevada, New Jersey, New York, North Carolina, Pennsylvania, Tennessee, Texas, Utah, Virginia, Oregon, West Virginia, Maryland, Montana and Wisconsin.
About two-thirds of Florida occupies a peninsula between the Gulf of Mexico and the Atlantic Ocean. Florida has the longest coastline in the contiguous United States, approximately , not including the contribution of the many barrier islands. Florida has a total of 4,510 islands that are ten acres or larger in area. This is the second-highest number of islands of any state of the United States; only Alaska has more. It is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. Much of the state is at or near sea level and is characterized by sedimentary soil. Florida has the lowest high point of any U.S. state. The climate varies from subtropical in the north to tropical in the south. The American alligator, American crocodile, American flamingo, Roseate spoonbill, Florida panther, bottlenose dolphin, and manatee can be found in Everglades National Park in the southern part of the state. Along with Hawaii, Florida is one of only two states that has a tropical climate, and is the only continental state with either a tropical climate or a coral reef. The Florida Reef is the only living coral barrier reef in the continental United States, and the third-largest coral barrier reef system in the world (after the Great Barrier Reef and Belize Barrier Reef).
In the 1930s, as part of the New Deal, the U.S. federal government constructed national parkways designed for recreational driving, and to commemorate historic trails and routes. As with other roads through national parks, these mostly undivided and two-lane parkways have lower speed limits, and are maintained by the National Park Service and the Federal Highway Administration jointly through the Federal Lands Transportation Program. An example is the Civilian Conservation Corps-built Blue Ridge Parkway in the Appalachian Mountains of North Carolina and Virginia. Others are: Skyline Drive in Virginia; the Natchez Trace Parkway in Mississippi, Alabama, and Tennessee; and the Colonial Parkway in eastern Virginia's Historic Triangle area. The George Washington Memorial Parkway and the Clara Barton Parkway, running along the Potomac River near Washington, D.C., were also constructed during this era.
The park is bordered on the north by the Lakemont neighborhood in the city of Bellevue and on the northeast by the city of Issaquah. The park is bounded on the east by the 260-acre Talus Open Space. State Route 900 forms the southeastern border. Neighboring Squak Mountain looms to the southeast and the farms of May Creek valley lie to the south. To the southwest is the city of Renton. The city of Newcastle, ranging over the Newport Hills occupies the western portion of Cougar Mountain, with several smaller parcels designated the China Creek Open Space abutting the park on the west and housing surrounding the Newcastle Golf Club directly to the west. To the northwest of the Red Town Trailhead is the deep gully of Coal Creek, with its own separate park, the Coal Creek Natural Area managed by the City of Bellevue which divides Newcastle from Bellevue. A 4-1/2 mile trail through the latter continues down to I-405. The park is fully within the Mountains to Sound Greenway.The hilltops of Cougar Mountain form a rough horseshoe-shape around the Klondike Marsh headwaters of Coal Creek, which runs northwest to Lake Washington through Coal Creek Park. Long Marsh Creek, Far Country Creek, Cabbage Creek, and Wilderness Creek are tributaries of May Creek, draining the south side of Cougar Mountain to Lake Washington. Deeply etching the sandstone precipice on the north and east side, Lewis Creek, Kline Creek, AA Creek, West Tibbets Creek, and Claypit Creek carry their water to Lake Sammamish.There are five named waterfalls within or near Cougar Mountain Regional Wildland Park.A notice on the official Cougar Mountain Regional Wildlands Park map cautions "Due to safety hazards from historical mining activities in this park you must stay on the trails identified on this map." Copies of the map are available at the major trailheads.
There are a few trails between the "official" ones in the park and the developed properties adjacent. Some of these trails are on non-county public property or private property unlikely to be developed due to wetness or access issues.
North Carolina () is a state in the southeastern region of the United States. It borders South Carolina and Georgia to the south, Tennessee to the west, Virginia to the north, and the Atlantic Ocean to the east. North Carolina is the 28th most extensive and the 9th most populous of the U.S. states. The state is divided into 100 counties. The capital is Raleigh, which along with Durham and Chapel Hill is home to the largest research park in the United States (Research Triangle Park). The most populous municipality is Charlotte, which is the second largest banking center in the United States after New York City.
Cougar Mountain Regional Wildland Park is a regional park in King County, Washington, near the towns of Bellevue and Issaquah. The park was established in June 1983 to protect the central core of Cougar Mountain, the park covers with of hiking trails and of equestrian trails. 
There are four major trailheads within the park. Maps are available at these trailheads, and there are directional signs at major trail intersections. Equestrian access is available at all but the first of these. Bicycles are not allowed on any trails.
Awards and press recognition have come to Cherry Springs and its staff. Thom Bemus, who initiated and coordinates the Stars-n-Parks program, was named DCNR's 2002 Volunteer of the Year. In 2007 the park's Dark Sky Programming and staff received the Environmental Education Excellence in Programming award from the Pennsylvania Recreation and Parks Society. Operations manager Chip Harrison and his wife Maxine, who directs the Dark Sky Fund, received a 2008 award from the Pennsylvania Outdoor Lighting Council for "steadfast adherence and active promotion of the principles of responsible outdoor lighting at Cherry Springs State Park". The DCNR has named Cherry Springs one of "25 Must-See Pennsylvania State Parks", specifically for having the "darkest night skies on the east coast". Cherry Springs State Park was featured in the national press in 2003 when "USA Today" named it one of "10 Great Places to get some stars in your eyes", in 2006 when "National Geographic Adventure" featured it in "Pennsylvania: The Wild, Wild East", and in "The New York Times" in 2007. All these were before it was named an International Dark Sky Park by the International Dark-Sky Association in 2008.
The park is home to a number of endangered species of flora and fauna. The forest area of the park houses over 1,000 plant species, 251 species of migratory, land and water birds, 50,000 species of insects and 40 species of mammals. In addition, the park also provides shelter to 38 species of reptiles, 9 species of amphibians, 150 species of butterflies and a large variety of fish.
In the U.S., the most well-known place for travertine formation is Yellowstone National Park, where the geothermal areas are rich in travertine deposits. Wyoming also has travertines in Hot Springs State Park in Thermopolis. Oklahoma has two parks dedicated to this natural wonder. Turner Falls, the tallest waterfall in Oklahoma, is a cascade of spring water flowing over a travertine cave. Honey Creek feeds this waterfall and creates miles of travertine shelves both up and downstream. Many small waterfalls upstream in the dense woods repeat the travertine-formation effect. The city of Davis now owns thousands of acres of this land and has made it a tourist attraction. Another travertine resource is in Sulphur, Oklahoma, east of Turner Falls. Travertine Creek flows through a spring-water nature preserve within the boundaries of the Chickasaw National Recreation Area.
In 1971, the federal government acquired many acres of the coastal islands in Escambia, Santa Rosa, and Okaloosa counties, preserving them from commercial development by establishing the Gulf Islands National Seashore, which also covers some islands off the Mississippi coast. Other beach areas protected by the state of Florida includeBoth state and federal parks offer facilities for camping, picnicking, and other recreational pursuits. In addition, some parts of the coastline are federal property belonging to Pensacola Naval Air Station, Eglin Air Force Base, and Tyndall Air Force Base, and so are likewise protected from commercial development.
Yellowstone National Park has one of the world's largest petrified forests, trees which were long ago buried by ash and soil and transformed from wood to mineral materials. This ash and other volcanic debris are believed to have come from the park area itself as the central part of Yellowstone is the massive caldera of a supervolcano. The park contains 290 waterfalls of at least , the highest being the Lower Falls of the Yellowstone River at .
Winfield Toll Bridge, also known as the Ross Booth Memorial Bridge, is a historic three-span cantilever Warren Truss bridge located at Winfield and Red House, Putnam County, West Virginia. It was built in 1955, and spans the Kanawha River, carrying West Virginia Route 34. The cantilever through-truss consists of two anchor spans each 245 feet in length and the main span 462 feet in length between pier center lines. The main span consists of two 128 feet, 4 inch, cantilever arms and a 205 feet, 4 inch, suspended span.
After the State Parks Commission of Louisiana was formed in 1934, 7 sites were acquired for use as state parks. During World War II, the rate of new park acquisition declined with the addition of only one new site, Sam Houston Jones State Park in 1944. In 1966, the National Park Service reviewed Louisiana's state parks system and made many recommendations, which led to specific guidelines and requirements for state parks. Over time, many state parks that did not meet these guidelines were either reclassified as state historic sites or were turned over to local or state agencies. Some of these parks include , Saline Bayou, and Black Lake. During the 1970s, government management of the state parks was restructured. The Office of State Parks was created, and 2 new parks were acquired. From 1995 to 2009, $80 million were invested in creating new facilities, or updating existing facilities.
Spencer has many acres of preserved parks and hiking areas such as the Burncoat Pond Wildlife Sanctuary which is protected by the Mass Audubon Society and Spencer State Forest/Howe State Park marking the birth place of inventor Elias Howe.
