The Jaghatai Mountain Range is a mountain range located in the western part of Razavi Khorasan Province in northeast Iran.
 Running in a northwest-southeast direction, the Jaghatai Range stretches from the west and southwest of the town of Jaghatai in the northwest to the northeast and east of the city of Sabzevar in the southeast.
 With an elevation of 2858 metres, Mount Nazargah is the highest point of the range.
 Mount Nazargah is situated in the central part of the range, northwest of the city of Sabzevar.
 The mountain range is located in a region with a cold semi-desert climate.
The Sierra Nacimiento (official name), or Nacimiento Mountains, are a mountain range in the northwestern part of the U.S. state of New Mexico.
 They are just west of the more prominent Jemez Mountains near the town of Cuba, and are separated from them by the Río Guadalupe and the Río de Las Vacas.
 This article will consider them as a unit together with the San Pedro Mountains, which are a smaller range contiguous with the Sierra Nacimiento on the north, and which are also part of the Nacimiento Uplift and lie at the edge of the greater San Juan Basin, which sits atop the Colorado Plateau.
 The combined range runs almost due north-south with a length of about 40 mi (65 km).
 The highest point in the combined range is the high point of the San Pedro Peaks, known unofficially as San Pedro Peak, 10,605 ft (3,232 m).
The Arno Trail (German: "Arnoweg" ) is an approximately 1200-km long-distance trail through the Austrian Alps.
 The highest point is atop the Sonnblick (3106 m.) near Bad Gastein, and in total the trail has over 57,000 m. of elevation gain.
 The highest elevations are in the western portion of the trail, in the Kalkberge, Pinzgauer Grasberge and Keesberge.
 The Arno Trail forms a loop which passes through such towns as Salzburg, Neukirchen, Bad Gastein and Nußdorf.
 It runs predominantly through Austria, although two stages pass through Germany's Berchtesgaden Alps and by the Königssee.
 The trail can be completed in just over 60 stages, many of which end at alpine huts run by the Austrian Alpine Club.
 It can be shortened by just under a week by crossing from Fuschl immediately to Salzburg in two stages and thus avoiding seven stages in the relatively low-lying foothills.
Bad Gastein (formerly "Badgastein") is a spa town in the district of St. Johann im Pongau, in the Austrian state of Salzburg.

The Bashagard Mountains or the Bashagerd Mountains (also known as Bashagird or Bashakerd) is a mountain range that is located in southeast of Iran.

 With an elevation of 2185 metres, Mount Buniken (Kuh-e Buniken) is the highest point of the range located in the western section of the Bashagard Mountains, east of Sardasht in Bashagard County in Hormozgan Province, and in the vicinity of a place that marks the borders of Kerman, Hormozgan, and Sistan and Baluchestan provinces.
 Made of ophiolite, an assemblage of mafic igneous rocks representing remnants of former oceanic crust, the mountain range was formed finally in the Miocene and the Pliocene during the Alpine orogeny.
 The mountain range is located in a region with a hot semi-desert climate.
The Tauern Railway Tunnel (German: "Tauerntunnel" ) in Austria is the longest tunnel of the Tauern Railway crossing the main chain of the Alps.
 Currently, it has a length of 8.371 km .
 The highest point of the tunnel, which is also the highest point in all of the railway line, is at 1226 m above sea level.
 The tunnel's north entrance is at Böckstein in the valley of Bad Gastein in the state of Salzburg, the south entrance near Mallnitz in Carinthia.
The Chehalem Mountains are a mountain range located in the Willamette Valley in the U.S. state of Oregon.
 Forming the southern boundary of the Tualatin Valley, the Chehalems are the highest mountains in the Willamette Valley.
 Composed of a single land mass that was uplifted by tectonic forces, the mountain range includes several spurs and ridges such as Parrett Mountain, Ribbon Ridge, and Bald Peak.
 The range extends from the Willamette River east of Newberg northwest to the foothills of the Oregon Coast Range south of Forest Grove.
 The highest peak in the Chehalem Mountain Range is Bald Peak, rising to 1629 ft , which is also the highest peak point within the Willamette Valley.
The Pinaleño Mountains are a remote mountain range in southeastern Arizona.
 They have over 7000 ft of vertical relief, more than any other range in the state.
 The mountains are surrounded by the Sonoran-Chihuahuan Desert.
 Subalpine forests cover the higher elevations.
 According to The Nature Conservancy, they traverse five ecological communities and contain "the highest diversity of habitats of any mountain range in North America."
 The highest point is Mount Graham at 10720 ft .
 Locals often refer to the whole mountain range as "Mount Graham", in which case the peak is referred to as "High Peak".
 The mountains cover 300 mi2 and are part of the Coronado National Forest, Safford ranger district.
The Level Mountain Range is a small but prominent mountain range occupying the broad summit of Level Mountain in northern British Columbia, Canada.
 Located between the Tuya River in the east and the Sheslay River in the west, it represents a high point on the Nahlin Plateau.
 The range is geologically younger than the main mass of Level Mountain, having formed in the last 7.1 million years.
 An eroded stratovolcano and several lava domes of Miocene-to-Pleistocene age comprise the Level Mountain Range.
 The highest point is Meszah Peak at the north end of the range with an elevation of 2166 m .
Serra da Estrela (] , "Star Mountain Range") is the highest mountain range in Continental Portugal.
 Together with the Serra da Lousã it is the westernmost constituent range of the Sistema Central and also one of the highest in the system.
 It includes mainland Portugal's highest point at 1993 m above mean sea level (although the summit of Mount Pico in the Portuguese Azores islands is higher).
 This point is not a distinctive mountain summit, but rather the highest point in a plateau, being known as Torre ("Tower" in English).
 Torre is an unusual summit in that it is accessible by a paved road.
 The peak has a topographic prominence of 1204 m and its parent peak is Pico Almanzor, in Spain.
