The Texas Hill Country is a geographical region located in the Edwards Plateau at the crossroads of West Texas, Central Texas, and South Texas.
 Given its geographical location, terrain features, and native vegetation, the Hill Country could be considered the beginning or end of the American Southwest (depending on which direction one is travelling).
 The region is notable for its karst topography and tall rugged hills of limestone or granite.
 Many of the hills rise to a height of 400-500 feet above the surrounding plains and valleys, with Packsaddle Mountain rising to a height of 800 feet above the Llano River in Kingsland.
 The Hill Country also includes the Llano Uplift and the second-largest granite dome in the United States, Enchanted Rock.
 The terrain throughout the region is punctuated by a thin layer of topsoil and a large number of exposed rocks and boulders, making the region very dry and prone to flash flooding.
 Native vegetation in the region includes various yucca, prickly pear cactus, desert spoon, and wildflowers in the Llano Uplift.
 The predominant trees in the region are ashe juniper and Texas live oak.
The Chuska Valley is a geographical region located in the northwestern portion of the U.S. state of New Mexico.
 Sitting atop the Colorado Plateau in the Four Corners region of the desert Southwest, it is near both Chacra Mesa and Chaco Canyon, which are noted for their Chacoan Anasazi ruins.
 The Chaco Slope is differentiated from the neighboring Gobernador Slope, Chaco Core, and Chaco Plateau by distinct surface water drainage patterns and geological formations.
 These regions were first labelled by archaeologist Gwinn Vivian.
 The valley is associated with the nearby Chuska Mountains.

The Urals (Russian: Ура́л ) are a geographical region located around the Ural Mountains, between the East European and West Siberian plains.
 It extends approximately from north to south, from the Arctic Ocean to the bend of Ural River near Orsk city.
 The boundary between Europe and Asia runs along the eastern side of the Ural Mountains.
 Ural mostly lies within Russia but also includes a part of northwestern Kazakhstan.
 This is a historical, not an official entity, with the boundaries overlapping its western Volga and eastern Siberia neighbor regions.
 At points in time, parts of the Urals were considered a gateway to Siberia, if not Siberia itself, or were combined with the Volga administrative divisions.
 At present time, there are two official namesake entities, the Ural Federal District and the Ural economic region.
 While the latter follows the historical boundaries, the former is a political product; the District omits Western Urals and includes Western Siberia instead.
Jurong (, Tamil: ஜூரோங் ) is a geographical region located at the south-westernmost point of the West Region of Singapore.
 Although mostly vaguely defined, the region's extent roughly covers the planning areas of Jurong East, Jurong West, Boon Lay, and Pioneer, along with Jurong Island in the Western Islands cluster and the southernmost portions of the Western Water Catchment.
 Should it be described at its greatest historical extent, the region can also include present-day Bukit Batok and Tuas as well.
 Jurong also covers several offshore islands as well, including Pulau Damar Laut and Pulau Samulun, both of which are located within the planning areas of Jurong East and Boon Lay respectively; along with the aforementioned Jurong Island.
 The coastline of the region on mainland Singapore, faces the strait of Selat Jurong, while the southernmost island of the region, Jurong Island, faces the strait of Selat Pandan.
The Lesser Poland Gorge of the Vistula (Polish: "Małopolski Przełom Wisły") is a geographical region located in central-eastern Poland, which administratively belongs to three Polish voivodeships – Lublin, Masovian, and Świętokrzyskie.
 The Gorge is for the most part made by the valley of the Vistula, with two Polish uplands on both sides of the river – Lesser Poland (or Małopolska) Upland to the west, and Lublin Upland to the east.
 The gorge is about 70 kilometers long, extending from the town of Zawichost in the south, to Puławy in the north.
 It is considerably narrow, only up to 3 kilometers wide.
 In some places, the banks of the Vistula valley are very steep, up to 70 meters above the water level.
