Question: How far is the protected area along the river near Babcock State Park?

full_context: Document 1: Linville Gorge Wilderness: The Linville Gorge Wilderness ("The Grand Canyon of North Carolina") is the third largest wilderness area in North Carolina (after Shining Rock Wilderness and Joyce-Kilmer Slickrock Wilderness) and one of only two wilderness gorges in the Southern United States (along with Bald River Gorge Wilderness in Tennessee). Maintained by the United States Forest Service, it comprises 11,786 acres (47.7 km) around the Linville River, and is situated inside the Pisgah National Forest. The river is approximately 1,400 feet (400 m) below the ridge, thus hiking in and out of the Gorge is challenging and enjoyable for those who like serious hiking. The plant and animal community is extremely diverse, with a dense hardwood/pine forest and a wide variety of smaller trees and other plants as well as bear, fox, raccoon, trout, grouse, wild turkey, vultures, owls, hawks, copperheads, and timber rattlesnakes.
Document 2: New River Coalfield: The New River Coalfield is located in northeastern Raleigh County and southern Fayette County, West Virginia. Commercial mining of coal began in the 1870s and thrived into the 20th century. The coal in this field is a low volatile coal, and the seams of coal that have been mined include Sewell, Fire Creek, and Beckley. This is very high quality bituminous coal rated at approximately 15,000 btu . The New River coalfield is named after the north flowing New River. Over 60 coal towns were once located there, supported by independent commercial districts at Beckley, Oak Hill, Mount Hope, and Fayetteville. By the 21st century many coal camps had partially or completely returned to nature. These company towns were located along Dunloup (Loup) Creek, Laurel Creek, White Oak Creek, lower Piney Creek, and, of course, the New River. The mainline of the Chesapeake and Ohio Railway ran right through the center of this coalfield, with spurs branching off in many directions, and rail yards were maintained at Quinnimont, Raleigh, and Thurmond, WV. The Virginian Railway's main line also passed through the western side of the field as well. Companies such as the New River Company, New River & Pocahontas Consolidated Coal Co., and Mary Frances Coal Co. were the largest operators in the New River Coalfield, but there were many smaller ones as well. These companies recruited native born whites, immigrants from Southern and Eastern Europe, and African-Americans from the South to work in their coal mines and railroads. The mines began to close down after World War II and today there are very few active coal mines in the field. The New River Gorge is now the domain of the National Park Service and they have done what their budget allows to preserve the coal heritage of the area.
Document 3: Bluestone Wildlife Management Area: Bluestone Wildlife Management Area (also known as Bluestone Lake Wildlife Management Area) is a wildlife management area in southern West Virginia surrounding Bluestone Lake and the New River. The section of the lake from just upstream of the Bluestone River to Bluestone Dam is in Bluestone State Park; the rest of the lake in West Virginia basin comprises Bluestone WMA. Altogether, the WMA comprises 18019 acre of land and water.
Document 4: Cumberland Falls State Resort Park: Cumberland Falls State Resort Park is a park located just southwest of Corbin, Kentucky and is contained entirely within the Daniel Boone National Forest. The park encompasses 1657 acre and is named for its major feature, 68 ft Cumberland Falls. The falls are one of the few places in the western hemisphere where a moonbow can frequently be seen on nights with a full moon. The park is also the home of 44 ft Eagle Falls.
Document 5: Beury Mountain Wildlife Management Area: Beury Mountain Wildlife Management Area is located on 9232 acre near Babcock State Park and New River Gorge National River in Fayette County, West Virginia. Beury Mountain's sloping terrain is covered with mixed hardwoods and oak-hickory second growth woodlands overlooking New River Gorge. Camping is not allowed at Beury Mountain WMA, but is available at nearby Babcock State Park.
Document 6: Little River Canyon National Preserve: Little River Canyon National Preserve is a United States National Preserve located on top of Lookout Mountain near Fort Payne, Alabama, and DeSoto State Park. Created by an act of Congress in 1992, the 15,288 acre preserve protects what is sometimes said to be the nation's longest mountaintop river, the Little River. The canyon was historically called "May's Gulf", "gulf" being a common term throughout the Cumberland Plateau for this sort of feature (e.g. Savage Gulf in Tennessee, or Trenton Gulf nearby in Georgia, now renamed "Cloudland Canyon"). Prior to being assigned to the National Park Service, the canyon area formed the southmost unit of Alabama's DeSoto State Park.
Document 7: Natural Bridge State Resort Park: Natural Bridge State Resort Park is a Kentucky state park located in Powell and Wolfe Counties along the Middle Fork of the Red River, adjacent to the Red River Gorge Geologic Area and surrounded by the Daniel Boone National Forest. Its namesake natural bridge is the centerpiece of the park. The natural sandstone arch spans 78 ft and is 65 ft high. The natural process of weathering formed the arch over millions of years. The park is approximately 2300 acre of which approximately 1200 acre is dedicated by the Kentucky State Nature Preserves Commission as a nature preserve. In 1981 this land was dedicated into the nature preserves system to protect the ecological communities and rare species habitat. The first federally endangered Virginia big eared bats, "Corynorhinus townsendii virginianus", recorded in Kentucky were found at Natural Bridge State Resort Park in the 1950s.
Document 8: Babcock State Park: Babcock State Park is a state park located along the New River Gorge on 4127 acre wooded in Fayette County, West Virginia. It is located approximately 20 miles away from the New River Gorge Bridge.
Document 9: Dorsey Knob: Dorsey Knob is a mountain summit located off U.S. Route 119 at the southern edge of Morgantown in Monongalia County, West Virginia, United States. Dorsey Knob is contained within a park spanning 71 acres (29 ha) that features the mountain's landmark Sky Rock (also referred to as Dorsey Knob). The top of Sky Rock is at an altitude of 1398 ft , rising nearly 600 feet (180 m) above the surrounding landscape. It overlooks the Monongahela River and the Appalachian Mountains. Also located in the park is Dorsey's Knob Lodge, operated by Boparc, Morgantown's municipal park authority.
Document 10: New River Gorge National River: The New River Gorge National River is a unit of the United States National Park Service designed to protect and maintain the New River Gorge in southern West Virginia. Established in 1978, the NPS-protected area stretches for 53 mi from just downstream of Hinton to Hawks Nest State Park near Ansted.
Document 11: Hawks Nest, West Virginia: Hawk's Nest, the site of Hawks Nest State Park, is a peak on Gauley Mountain in Ansted, West Virginia, USA. The cliffs at this point rise 585 ft (178 m) above the New River. Located on the James River and Kanawha Turnpike (the road that served as an extension of the canal across what is now West Virginia), many early travelers on this road stopped to see the view of the river below. In modern times, the Midland Trail carries U.S. Route 60 through the same general route. Ample parking at the overlook in the state park provides tourists with free access to the views.
Document 12: Coal camps in Fayette County, West Virginia: The coal towns, or "coal camps" of Fayette County, West Virginia were situated to exploit the area's rich coal seams. Many of these towns were located in deep ravines that afforded direct access to the coal through the hillsides, allowing mined coal to be dropped or conveyed downhill to railway lines at the valley floor. Many of these encampments were set up as company towns, and when their mines closed, the towns vanished. A few, like Thurmond, West Virginia, have survived in a reduced state. Fayette County covers portions of three coalfields: the New River Coalfield, the Kanawha Coalfield and the Greenbrier Coalfield. Below is a partial list of known coal towns within the three coalfields: the New River Coalfield, the Kanawha Coalfield and the Greenbrier Coalfield. More may be found
