full_context: Document 1: Tennessee: Summers in the state are generally hot and humid, with most of the state averaging a high of around 90 °F (32 °C) during the summer months. Winters tend to be mild to cool, increasing in coolness at higher elevations. Generally, for areas outside the highest mountains, the average overnight lows are near freezing for most of the state. The highest recorded temperature is 113 °F (45 °C) at Perryville on August 9, 1930 while the lowest recorded temperature is −32 °F (−36 °C) at Mountain City on December 30, 1917.
Document 2: Appalachian Mountains: The range is mostly located in the United States but extends into southeastern Canada, forming a zone from 100 to 300 mi (160 to 480 km) wide, running from the island of Newfoundland 1,500 mi (2,400 km) southwestward to Central Alabama in the United States.[discuss] The range covers parts of the islands of Saint Pierre and Miquelon, which comprise an overseas territory of France. The system is divided into a series of ranges, with the individual mountains averaging around 3,000 ft (910 m). The highest of the group is Mount Mitchell in North Carolina at 6,684 feet (2,037 m), which is the highest point in the United States east of the Mississippi River.
Document 3: Tunnel Reservoir: Tunnel Reservoir is an artificial lake and recreational area located in the White Mountains around the town of Greer, Arizona. This reservoir is one of three lakes known as the Greer Lakes. The Greer Lakes include Bunch, Tunnel and River Reservoirs, and are a short distance apart from each other. The boating facility offers a boat launching area, boat trailer parking, restrooms, and space for recreational vehicles. The reservoir is stocked with Rainbow and Brown trout species.
Document 4: Turtle-Flambeau Flowage: The Turtle-Flambeau Flowage was created in 1926 when the "Chippewa and Flambeau Improvement Company" built a dam on the Flambeau River downstream from its confluence with the Turtle River. The dam flooded 16 natural lakes and formed an impoundment of approximately 14,000 acres.
Document 5: Keyhole State Park: The Keyhole Reservoir, an impoundment of the Belle Fourche River, was formed by the Keyhole Dam project of the United States Bureau of Reclamation, completed in 1952. The reservoir has a total capacity of 334,200 acre-feet and water surface of 13,700 acres, which provides storage for irrigation, flood control, fish and wildlife conservation, recreation, sediment control, and municipal and industrial water supply. Although located in Wyoming, the reservoir's waters are allocated by compact to go 90 percent to South Dakota and 10 percent to Wyoming.
Document 6: Mount Mitchell: Mount Mitchell is the highest peak of the Appalachian Mountains and the highest peak in mainland eastern North America. It is located near Burnsville in Yancey County, North Carolina, in the Black Mountain subrange of the Appalachians, and about 19 miles (31 km) northeast of Asheville. It is protected by Mount Mitchell State Park and surrounded by the Pisgah National Forest. Mount Mitchell's elevation is 6,684 feet (2,037 m) above sea level.
Document 7: Tellico Reservoir: Tellico Reservoir, also known as Tellico Lake, is a reservoir in Tennessee, created by the Tennessee Valley Authority (TVA) in 1979 upon the completion of Tellico Dam. The dam impounds the Little Tennessee River and the lower Tellico River. While TVA is careful to refer to its artificial lakes as reservoirs (such as "Tellico Reservoir"), common usage tends to refer to the reservoir as "Tellico Lake". The lake is approximately 16,000 acres in surface area and provides 357 miles of shoreline.
Document 8: Appalachian Trail: New York's 88.4 miles (142.3 km) of trail contain very little elevation change compared to other states. From south to north, the trail summits many small mountains under 1,400 feet (430 m) in elevation, its highest point in New York being Prospect Rock at 1,433 feet (437 m), and only 3,000 feet (910 m) from the border with New Jersey. The trail continues north, climbing near Fitzgerald Falls, passing through Sterling Forest, and then entering Harriman State Park and Bear Mountain State Park. The lowest point on the entire Appalachian Trail is in the Bear Mountain Zoo 124 feet (38 m). It crosses the Hudson River on the Bear Mountain Bridge. It then passes through Fahnestock State Park, and continues northeast and crosses the Metro - North Railroad's Harlem Line. This track crossing is the site of the only train station along the trail's length. It enters Connecticut via the Pawling Nature Reserve. The section of the trail that passes through Harriman and Bear Mountain State Parks is the oldest section of the trail, completed in 1923. A portion of this section was paved by 700 volunteers with 800 granite - slab steps followed by over a mile of walkway supported by stone crib walls with boulders lining the path. The project took four years, cost roughly $1 million, and was officially opened in June 2010. The project was done by the New York -- New Jersey Trail Conference. The New York -- New Jersey Trail Conference maintains and updates the Appalachian Trail in New York.
Document 9: Pickwick Lake: Pickwick Lake is the reservoir created by Pickwick Landing Dam as part of the Tennessee Valley Authority. The lake stretches from Pickwick Landing Dam to Wilson Dam.
Document 10: Tennessee: The highest point in the state is Clingmans Dome at 6,643 feet (2,025 m). Clingmans Dome, which lies on Tennessee's eastern border, is the highest point on the Appalachian Trail, and is the third highest peak in the United States east of the Mississippi River. The state line between Tennessee and North Carolina crosses the summit. The state's lowest point is the Mississippi River at the Mississippi state line (the lowest point in Memphis, nearby, is at 195 ft (59 m)). The geographical center of the state is located in Murfreesboro.
Document 11: Tennessee: Most of the state has a humid subtropical climate, with the exception of some of the higher elevations in the Appalachians, which are classified as having a mountain temperate climate or a humid continental climate due to cooler temperatures. The Gulf of Mexico is the dominant factor in the climate of Tennessee, with winds from the south being responsible for most of the state's annual precipitation. Generally, the state has hot summers and mild to cool winters with generous precipitation throughout the year, with highest average monthly precipitation generally in the winter and spring months, between December and April. The driest months, on average, are August to October. On average the state receives 50 inches (130 cm) of precipitation annually. Snowfall ranges from 5 inches (13 cm) in West Tennessee to over 16 inches (41 cm) in the higher mountains in East Tennessee.
Document 12: Tellico Blockhouse: The Tellico Blockhouse was an early American outpost located along the Little Tennessee River in Vonore, Monroe County, Tennessee. Completed in 1794, the blockhouse operated until 1807 with the purpose of keeping the peace between nearby Overhill Cherokee towns and early Euro-American settlers in the area in the wake of the Cherokee–American wars. The Tellico Blockhouse was the site where several treaties were negotiated in which the Cherokee were induced to cede large portions of land in Tennessee and Georgia. During this period, the blockhouse was the site of official liaisons between the United States government and the Cherokee.
Document 13: Chickamauga Lake: Chickamauga Lake is a reservoir in the United States along the Tennessee River created when the Chickamauga Dam, as part of the Tennessee Valley Authority, was completed in 1940. The lake stretches from Watts Bar Dam at mile 529.9 (853 km) to Chickamauga Dam at mile 471.0 (758 km) making the lake 58.9 miles (94.8 km) long. It borders Rhea County, Meigs County, and Hamilton County with 810 miles (1,303 km) of shoreline and two bridges crossing it at State Highway 60 and Highway 30. The lake is commonly used for recreational and outdoor activities, especially at the southern end, due to the high population density surrounding it. It was named after the Chickamauga (tribe) of Cherokees who used to live in the area.
