Mount Raimer, 2572 ft , is a prominent peak in the Taconic Mountains of western Massachusetts and adjacent New York.
 The west side and summit are located in New York; the east slopes lie within Massachusetts.
 The summit ridge is part meadow and part wooded with red spruce, balsam fir, and northern hardwood tree species.
 It is notable for its views of the Hoosic River valley and Hudson River Valley.
 The 35 mi Taconic Crest Trail traverses the mountain.
 Much of the upper slopes and summit are within protected conservation land.
 The mountain is the location of a defunct ski area.
Abies fraseri, the Fraser fir, is a species of fir native to the Appalachian Mountains of the Southeastern United States.
The Sugarland Mountain Trail is an American hiking trail, in the Great Smoky Mountains National Park of Sevier County, Tennessee.
 The trail traverses Sugarland Mountain, a massive ridge running perpendicular to the main crest of the Smokies and effectively dividing the park's north-central section from its northwestern section.
 Sugarland Mountain is flanked by the deep upper valleys of two of the park's major watersheds— the West Fork of the Little Pigeon River (to the east) and Little River (to the west).
 The trail passes through several forest types, including deciduous forest at lower elevations, heaths ("hells") along the mountain's backbone formations, and a stand of Southern Appalachian spruce-fir forest in the upper elevations.
 Occasional breaks in the foliage allow for views of Mount Le Conte and Sevier County to the east and Blanket Mountain and the ridges above Elkmont to the west.
Pitcher Mountain is a 2,153 feet (656 m) monadnock located in southwest New Hampshire.
 The mountain is traversed by the 50 mile (80 km) Monadnock-Sunapee Greenway and offers 360 degree views from its open summit.
 Lower elevations are wooded with species of the northern hardwood forest type; small stands of coniferous red spruce cling to the upper slopes.
 A fire tower stands on the summit and a beef livestock farm occupies the east shoulder of the mountain.
 Pitcher Mountain is part of an extensive area of heath barrens and blueberry fields that continue north over Hubbard Hill and Jackson Hill.
Roan Mountain is the highpoint of the Roan-Unaka Range of the Southern Appalachian Mountains, located in the Southeastern United States.
 The mountain is clad in a dense stand of Southern Appalachian spruce-fir forest, and includes the world's largest natural rhododendron garden, and the longest stretch of grassy bald in the Appalachian range.
 The Cherokee National Forest and Pisgah National Forest converge atop the mountain, with Roan Mountain State Park located near its northern base.
 The Appalachian Trail crosses most of the Roan's crest.
 The Roan High Knob Shelter is the highest backcountry shelter on the entire 2174 mi trail.
The Black Mountains are a mountain range in western North Carolina, in the southeastern United States.
 They are part of the Blue Ridge Province of the Southern Appalachian Mountains.
 The Blacks are the highest mountains in the Eastern United States.
 The range takes its name from the dark appearance of the red spruce and Fraser fir trees that form a spruce-fir forest on the upper slopes which contrasts with the brown (during winter) or lighter green (during the growing season) appearance of the deciduous trees at lower elevations.
 The Eastern Continental Divide, which runs along the eastern Blue Ridge crest, intersects the southern tip of the Black Mountain range.
Elliott Knob is one of the highest mountains in the northern portions of the U.S. state of Virginia.
 At 4463 ft , the peak is located on the ridge known as Great North Mountain.
 A subpeak known simply as "Hogback" (4447 ft ) is located .50 mi to the southwest.
 A small, naturally growing stand of red spruce trees are on the summit, and the upper slopes also have yellow birch and sugar maple, indicating that the altitude is just high enough to support tree species normally found hundreds of miles to the north.
 Otherwise oak and hickory trees are the most common types found on the mountain.
 The mountain is entirely within George Washington and Jefferson National Forests.
The conifer swift moth ("Korscheltellus gracilis") is a swift moth considered a forest pest in eastern and central North America, from Canada south to North Carolina.
 Larvae feed primarily on roots of evergreen trees, and are weakly polyphagous, able to survive on deciduous trees (e.g. birches, "Betula") but preferring balsam fir and red spruce.
 They penetrate bark, but lesions on roots are shallow.
 These wounds may, however, provide easy entry for pathogenic fungi and nematodes. "K. gracilis" has been shown to reduce survival on saplings, but adult trees have been found with more than 30 feeding scars on their roots.
 But trees that are weakened by air pollution or changes in soil chemistry may invite "K. gracilis" infestation.
 Adults can be found in woody areas between June and August.
 They are cryptically colored, but are active for 20–40 minutes each dawn and twilight, and occasionally come to light.
 In the conifer swift moth, courtship, mating, and egg laying occur during evening hours; only oviposition occurs in the morning.
 They are Exoporia, and females scatter eggs while in flight.
 It takes two years for the larvae to mature, so populations tend towards two-year cycles.
 Females emit pheromones to attract males, from organs on their hind wings.
The Appalachian temperate rainforest is located in the southern Appalachian Mountains of the eastern U.S.
 About 351,500 square kilometers (135,000 square miles) of forest land is spread across southwestern Virginia, western North Carolina, northern Georgia, and eastern Tennessee.
 The annual precipitation is more than 60 inches (over 1500mm).
 The Southern Appalachian spruce–fir forest is a temperate rainforest located in the higher elevations in southwestern Virginia and western North Carolina.
 Fir is dominant at higher elevation, spruce at middle elevation, and mixed forests at low elevation.
Saguramo Range (Georgian: საგურამოს ქედი ) is an east-west mountain range in Eastern Georgia located immediately to the north of the city of Tbilisi.
 The highest mountain of the range is Mt. Saguramo at an elevation of 1,392 meters (4,567 ft.) above sea level.
 The Saguramo Range forms the western extension of the Ialno Range.
 The geologic makeup of the mountains consists of neogene sandstone, clay and conglomerates.
 The area lies in a moderately humid subtropical zone and the slopes of the Saguramo Range are mainly covered by deciduous forests consisting of hornbeam, oak, and maple at lower elevations with beech taking over at higher elevations.
 The understory layer also includes evergreen elements characteristic of Colchian forests.

Question: The Black Mountains are a mountain range in western North Carolina, the range takes its name from the dark appearance of the red spruce and which species of fir native to the Appalachian Mountains of the Southeastern United States, that form a spruce-fir forest on the upper slopes which contrasts with the brown (during winter) or lighter green (during the growing season) appearance of the deciduous trees at lower elevations? 
Answer: Fraser fir
