Djibouti is a country in the Horn of Africa. It is bordered by Eritrea in the north, Ethiopia in the west and south, and Somalia in the southeast. To the east is its coastline on the Red Sea and the Gulf of Aden. Rainfall is sparse, and most of the territory has a semi-arid to arid environment. Lake Assal is a saline lake which lies 155 m (509 ft) below sea level, making it the lowest point on land in Africa and the third-lowest point on Earth after the Sea of Galilee and the Dead Sea. Djibouti has the fifth smallest population in Africa. Djibouti's major settlements include the capital Djibouti City, the port towns of Tadjoura and Obock, and the southern cities of Ali Sabieh and Dikhil. It is the forty-six country by area in Africa and 147st largest country in the world by land area, covering a total of 23,200 km2 (9,000 sq mi), of which 23,180 km2 (8,950 sq mi) is land and 20 km2 (7.7 sq mi) is water.

The town is located on the N3 freeway, connecting it with the rest of South Africa.
The Gatun Dam is an earthen dam across the Chagres River in Panama, near the town of Gatun. The dam, constructed between 1907 and 1913, is a crucial element of the Panama Canal; it impounds the artificial Gatun Lake, which carries ships 33 kilometres (21 mi) of their transit across the Isthmus of Panama. In addition, a hydro-electric generating station at the dam generates electricity which is used to operate the locks and other equipment in the canal.
Mount Nebo is the southernmost and highest mountain in the Wasatch Range of Utah, in the United States, and the centerpiece of the Mount Nebo Wilderness, inside the Uinta National Forest. It is named after the biblical Mount Nebo in Jordan, overlooking Israel from the east of the Jordan River, which is said to be the place of Moses' death.
Cadair Berwyn, Cader Berwyn or Craig Uchaf is a mountain summit in north-east Wales with a height of 832 metres (2,730 ft) above sea level. It is the highest point in the Berwyn range, the highest in North East Wales and the highest significant summit in Wales outside the National Parks. Cadair Berwyn and Foel Cedig to the west are the two Marilyns that form the Berwyn range. The undulating plateau of the range also includes a large number of other summits above 2,000 feet (610 m), including satellite summits of Cadair Berwyn and many which are classed as Nuttalls.
Lake Sonoma is a reservoir west of Cloverdale in northern Sonoma County, California, created by the construction of Warm Springs Dam. The lake provides water for countywide growth and development, and for recreation.
Lake Khövsgöl is a lake in Khövsgöl Province, Mongolia. It is the largest freshwater lake in the country by volume and second largest by area after Uvs Lake. It is nicknamed the "Younger sister" of those two "sister lakes".
Hindmarsh Island is an inland river island located in the lower Murray River near the town of Goolwa, South Australia.
The Grimsel Pass is a mountain pass in Switzerland, crossing the Bernese Alps at an elevation of 2,164 metres (7,100 ft). The pass connects the Haslital, the upper valley of the river Aare, with the upper valley of the Rhône. In so doing, and as the Aare is a tributary of the Rhine, the pass crosses the continental divide between the North Sea and the Mediterranean Sea.
Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.
Hoodoo Mountain, sometimes referred to as Hoodoo Volcano, is a potentially active stratovolcano in the Northern Interior of British Columbia, Canada. It is located 25 kilometres northeast of the Alaska–British Columbia border on the north side of the Iskut River opposite of the mouth of the Craig River. With a summit elevation of 1,850 metres and a topographic prominence of 900 metres, Hoodoo Mountain is one of many prominent peaks within the Boundary Ranges of the Coast Mountains. Its flat-topped summit is covered by an ice cap more than 100 metres thick and at least 3 kilometres in diameter. Two valley glaciers surrounding the northwestern and northeastern sides of the mountain have retreated significantly over the last hundred years. They both originate from a large icefield to the north and are the sources of two meltwater streams. These streams flow along the western and eastern sides of the volcano before draining into the Iskut River.
Mount Edziza, sometimes called Edziza Mountain or Edziza Peak, is a stratovolcano in Cassiar Land District of northwestern British Columbia, Canada. It is located on the Big Raven Plateau of the Tahltan Highland which extends along the western side of the Stikine Plateau. The mountain has an elevation of 2,786 metres, making it the highest volcano of the Mount Edziza volcanic complex. However, it had an elevation of at least 3,396 metres before its original summit was likely destroyed by a violent, climactic eruption in the geologic past; its current flat summit contains an ice-filled, 2-kilometre (1.2-mile) in diameter crater. Mount Edziza contains several lava domes, cinder cones and lava fields on its flanks, as well as an ice cap that is characterized by several outlet glaciers stretching out to lower altitudes. All sides of the mountain are drained by tributaries of Mess Creek and Kakiddi Creek which are situated within the Stikine River watershed.
Level Mountain is a large volcanic complex in the Northern Interior of British Columbia, Canada. It is located 50 kilometres north-northwest of Telegraph Creek and 60 kilometres west of Dease Lake on the Nahlin Plateau. With a maximum elevation of 2,164 metres, it is the second-highest of four large complexes in an extensive north–south trending volcanic region. Much of the mountain is gently-sloping; when measured from its base, Level Mountain is about 1,100 metres tall, slightly taller than its neighbour to the northwest, Heart Peaks. The lower, broader half of Level Mountain consists of a shield-like structure while its upper half has a more steep, jagged profile. Its broad summit is dominated by the Level Mountain Range, a small mountain range with prominent peaks cut by deep valleys. These valleys serve as a radial drainage for several small streams that flow from the mountain. Meszah Peak is the only named peak in the Level Mountain Range.
Top o'Selside is a hill in the Lake District in Cumbria, England. At 335 metres (1,099 ft), it is the highest point of the group of hills situated between Coniston Water and Windermere. This group also includes the Wainwright of Black Fell and the summits of Black Brows and Rusland Heights. Top o'Selside lies not in the centre of this region, but in the south-western corner, just outside the forestry plantations of Grizedale Forest and only two-thirds of a mile from the eastern shore of Coniston Water. This large separation from any higher ground gives it enough relative height to make it a Marilyn.
The Dinkey Lakes Wilderness is a federally designated wilderness area located 45 miles (72 km) northeast of Fresno, in the state of California, United States. It comprises 30,000 acres (12,141 ha) within the Sierra National Forest and was added to the National Wilderness Preservation System by the California Wilderness Act of 1984. Elevations range from 8,200 feet (2,500 m) to 10,619 feet (3,237 m). Recreational activities in the wilderness include day hiking, backpacking, horseback riding, fishing, rock climbing and cross-country skiing.
Matka is a canyon located west of central Skopje, North Macedonia. Covering roughly 5,000 hectares, Matka is one of the most popular outdoor destinations in North Macedonia and is home to several medieval monasteries. The Matka Lake within the Matka Canyon is the oldest artificial lake in the country.
Height above mean sea level is a measure of a location's vertical distance in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods. Climate change and other forces can cause sea levels and elevations to vary over time.
