Query: What mountain ranges are found in Ethiopia?
The Ethiopian Highlands is a rugged mass of mountains in Ethiopia, situated in the Horn region in northeast Africa. It forms the largest continuous area of its elevation in the continent, with little of its surface falling below 1,500m (4,900ft), while the summits reach heights of up to 4,550m (14,930ft). It is sometimes called the Roof of Africa due to its height and large area.[1] Most of the Ethiopian Highlands are part of central and northern Ethiopia, and its northernmost portion reaches into Eritrea.
The Arrei Mountains also known as the "Roof of Ali Sabieh", are a mountain range in the southern Ali Sabieh Region in Djibouti. With an average elevation of above sea level, is the sixth highest point in Djibouti, they are situated near the border with Ethiopia. The mountains constitute the highest point in Ali Sabieh region. The Issa Somali have a long history in the Arrei Mountains.
With the introduction of Islam in the 7th century in what are now the Afar-inhabited parts of Eritrea and Djibouti, the region began to assume a political character independent of Ethiopia. Three Islamic sultanates were founded in and around the area named Shewa (a Semitic-speaking sultanate in eastern Ethiopia, modern Shewa province and ruled by the Mahzumi dynasty, related to Muslim Amharas and Argobbas), Ifat (another Semitic-speaking sultanate located in eastern Ethiopia in what is now eastern Shewa) and Adal and Mora (Gadabursi Clan, Somali, and Harari vassal sultanate of Ifat by 1288, centered on Dakkar and later Harar, with Zeila as its main port and second city, in eastern Ethiopia and in Somaliland's Awdal region; Mora was located in what is now the southern Afar Region of Ethiopia and was subservient to Adal).

Entoto Mountains • Mount Entoto • Erta Ale Range • Ethiopian Highlands 
About 9° N there is a break in the wall, through which the Awash River flows eastward. The main range at this point trends southwest, while south of the Awash Valley, which is some below the level of the mountains, another massif rises in a direct line south. This second range sends a chain (the Ahmar Mountains) eastward toward the Gulf of Aden.
Also found within the vicinity of the mountain range are streams that flow through waterfalls, cascades and rapids. Wetlands and marshes, although not significant in area, are also found within the range. The mountain range manifests a radial type of drainage pattern.
The first trail was cut at Sugarloaf in 1950 by the Sugarloaf Mountain Ski Club and a group of locals known as "The Bigelow Boys". Led by Amos Winter, along with Stub Taylor, they transformed the mountain into what is today one of the largest ski areas in the Northeast. The founding of the mountain was called for by the US ski association. Thy hired Pheous Sprague to find a mountain in Maine. Initially, they planned to have the mountain on the Bigelow mountain range, but when flagstaff lake was made the plans had to be scrapped. Phin Sprague then found Amos and Stub which knew of a mountain called Sugarloaf. Many documents relating to the founding and early years now reside at the Ski Museum of Maine in Kingfield, Maine.
Habitats of the Bale Mountains National Park range from grassland areas around in elevation, to Mount Tullu Demtu, the second highest point in Ethiopia at above sea level.
The Harenna shrew ("Crocidura harenna") is a white-toothed shrew found only in one location in the Bale Mountains in southern Ethiopia. It occurs within an area of less than ten square kilometres, and is listed as a critically endangered species, due to habitat loss and a restricted range.
An island range is a mountain range that exists in total or almost total isolation from a larger chain of ranges and sub-ranges. From a distance on the plains, these ranges appear as "islands" of higher ground. They are often described as islands of mountainous land because they exist in the "sea" of lower elevation and flatter prairie country; many examples are found in the northern Rocky Mountains of the United States. Island ranges include the Big Snowy Mountains of east-central Montana, the Crazy Mountains of south-central Montana, or the Wichita Mountains of southwestern Oklahoma. Island ranges, due to their isolation, often have animal and/or plant species or subspecies found nowhere else.
Predominantly Mexico, but some species are found ranging as far south as northern South America. "D. australis" occurs at least as far south as southwestern Guatemala, while "D. coccinea" and "D. imperialis" also occur in parts of Central America and northern South America. "Dahlia" is a genus of the uplands and mountains, being found at elevations between 1,500 and 3,700 meters, in what has been described as a "pine-oak woodland" vegetative zone. Most species have limited ranges scattered throughout many mountain ranges in Mexico 
The northeast African mole-rat is native to upland areas of Ethiopia, Somalia, and northwest Kenya. It is found at elevations of up to in Ethiopia and up to in other parts of its range. It is an adaptable species and able to live in a range of habitats including savanna, moist tropical forest, agricultural land, pasture, coffee plantations and gardens.
Mount Afdem is a mountain range in Ethiopia. With an average elevation of .
Friedmann's lark is found in southern Ethiopia, central and south-eastern Kenya, and north-eastern Tanzania, but its population and exact range are very poorly known. The type specimen was collected in Ethiopia (from the Konso-Sagan area) in 1992, having been seen only one time since, in 1998; but most of what is known comes primarily from data collected in Tsavo East and West National Parks, in Kenya. There are also a few records from Tanzania, from Mkomazi Game Reserve, south of Arusha.
"Monardella odoratissima" is found in montane forests above 600 m. and below 3100 m. It is found in many Northern California mountain ranges, including the Klamath Mountains and the North California Coast Ranges, the Cascade Range, the Sierra Nevada, the Modoc Plateau, White Mountains and Inyo Mountains. It is found outside California, as far north as Washington, and in Nevada and Utah.
The Scott Bar Mountains are a mountain range in Siskiyou County, California. The area is named after gold miner John W. Scott who found a large gold nugget at what is now the town of Scott Bar.
The Bale Mountains are separated from the larger part of the Ethiopian highlands by the Great Rift Valley, one of the longest and most profound chasms in Ethiopia. The highest peaks of that range include Tullu Demtu, the second-highest mountain in Ethiopia (), Batu (), Chilalo () and Mount Kaka ().
Simien Mountains National Park is one of the national parks of Ethiopia. Located in the Semien (North) Gondar Zone of the Amhara Region, its territory covers the Semien Mountains and includes Ras Dashan, the highest point in Ethiopia.
It is home to a number of endangered species, including the Ethiopian wolf and the walia ibex, a wild goat found nowhere else in the world. The gelada baboon and the caracal, a cat, also occur within the Simien Mountains. More than 50 species of birds inhabit the park, including the impressive bearded vulture, or lammergeier, with its 10-foot (3 m) wingspan.

The following notable mountains and mountain ranges are completely or partially within the borders of Ethiopia:
The vervet monkey ranges throughout much of Southern and East Africa, being found from Ethiopia, Somalia and extreme southern South Sudan, to South Africa. It is not found west of the East African Rift or the Luangwa River, where it is replaced by the closely related malbrouck ("C. cynosuros"). The vervet monkey inhabits savanna, riverine woodland, coastal forest and mountains up to 4000 m (13,100 ft). They are adaptable and able to persist in secondary and/or highly fragmented vegetation, including cultivated areas, and sometimes are found living in both rural and urban environments. Annual home range size has been observed to be as high as 176 ha with an average population density of 54.68 animals/km².
A mountain range or hill range is a series of mountains or hills ranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets.
