Ubsunur Hollow: Ubsunur Hollow (also Uvs Nuur Basin or Uvs Lake Basin; Mongolian: Увс нуурын хотгор, "Uws núrīn hotgor") is a fragile mountain endorheic basin or hollow located on the territorial border of Mongolia and the Republic of Tuva in the Russian Federation, named after Uvs Lake, a large, shallow and very saline lake in the basin's center.  Several smaller lakes are scattered throughout.  It is part of a combination of raised lands and hollows located throughout the Tannu-Ola and Altai mountainous regions.  Here, the world's most northern desert meets the Northern Hemisphere's most southern tundra zone.  The Ubsunur Hollow was inscribed on the World Heritage Site in 2003.

Uvs Lake: Uvs Lake (Mongolian: Увс нуур, "Uws núr" ; Russian: озеро Убсу-Нур, "ozero Ubsu-Nur" , Ubsu-Nur lake) is a highly saline lake in an endorheic basin - Uvs Nuur Basin in Mongolia with a small part in Russia.  It is the largest lake in Mongolia by surface area, covering 3,350 km² at 759 m above sea level.

Great Divide Basin: The Great Divide Basin or Great Divide Closed Basin is an area of land in Wyoming's Red Desert (United States) where none of the water falling as rain to the ground drains into any ocean, directly or indirectly.  It is therefore considered an endorheic basin, and it adjoins the Continental Divide in southern Wyoming.  To the west of the basin is the Green River watershed, draining to the Gulf of California/Pacific Ocean; to the east is the North Platte watershed, draining to the Gulf of Mexico/Atlantic Ocean.  The basin is very roughly rectangular in shape; the northwest corner is in the Wind River Range near South Pass, about 40 mi southwest of Lander, and the southeast corner is in the Sierra Madre Range near Bridger Pass, about 20 mi southwest of Rawlins.

Chad Basin: The Chad Basin is the largest endorheic basin in Africa, centered on Lake Chad.  It has no outlet to the sea and contains large areas of desert or semi-arid savanna.  The drainage basin is roughly coterminous with the sedimentary basin of the same name, but extends further to the northeast and east.  The basin spans seven countries, including most of Chad and a large part of Niger.  The region has an ethnically diverse population of about 30 million people as of 2011, growing rapidly.

Godzareh depression: The Gowd-i zerrah, i.e., Zerrah Depression (Persian for "lake depression") is the lowest part of an inland drainage basin covering large parts of southern Afghanistan and Iran known as the Sistan Basin.  The Sistan Basin is an endorheic basin and encompasses a complex system of rivers, shallow lakes, marshes and wetlands as its watershed, draining into the Hamun Lakes in southeastern Iran.  Occasional outflows from these lakes are carried back into Afghanistan by the seasonal Shile river to the basin's terminus, the Godzareh depression in Afghanistan.  The depression is flat and very shallow with fine textured sediment at its lowest portions.  The lowest section of the Godzareh depression is 467 m above sea level.  The depression only receives runoff water when the main tributaries are overflowing every 10 years on the average.

Üüreg Lake: Üüreg Lake (Mongolian: Үүрэг нуур , "Üüreg nuur") is a saline lake in an endorheic basin in western Mongolia, north-west of the Great Lakes Hollow, near the western edge of the Uvs Nuur basin.  The Tsagaan river gorge (Mongolian: "Tsagaan Shuvuut Uul") lies on the west side of the lake.

Lake Eyre basin: The Lake Eyre basin ( ) is a drainage basin that covers just under one-sixth of all Australia.  The Lake Eyre Basin is the largest endorheic basin in Australia and amongst the largest in the world, covering about 1200000 km2 , including much of inland Queensland, large portions of South Australia and the Northern Territory, and a part of western New South Wales.

Harney Basin: The Harney Basin is an endorheic basin in southeastern Oregon in the United States at the northwestern corner of the Great Basin.  One of the least populated areas of the contiguous United States, it is located largely in northern Harney County, bounded on the north and east by the Columbia Plateau—within which it is contained, physiographically speaking—and on the south and west by a volcanic plain.  The basin encompasses an area of 1490 mi2 in the watershed of Malheur Lake and Harney Lake.  Malheur Lake is a freshwater lake, while Harney Lake is saline-alkaline.

Addis Ababa: Addis Ababa (Amharic: አዲስ አበባ "Addis Abäba " ] , "new flower"; Oromo: "Finfinne" , ] "Natural Spring(s)") or Addis Abeba (the spelling used by the official Ethiopian Mapping Authority), is the capital and largest city of Ethiopia.  It has a population of 3,384,569 according to the 2007 population census, with annual growth rate of 3.8%.  This number has been increased from the originally published 2,738,248 figure and appears to be still largely underestimated.

Lake Awasa: Lake Awasa is an endorheic basin in Ethiopia, located in the Main Ethiopian Rift south of Addis Ababa.  According to the "Statistical Abstract of Ethiopia for 1967/68", the lake is 16 km long and 9 km wide, with a surface area of 129 square kilometers.  It has a maximum depth of 10 meters and is located at an elevation of 1,708 meters.
