Sand Mountain (Alabama): Sand Mountain is a sandstone plateau in northeastern Alabama and (to a far lesser extent) northwestern Georgia.  It is part of the southern tip of the Appalachian mountain chain and it is the largest plateau in the chain.  Geologically a continuation of Walden Ridge, Sand Mountain is part of the Cumberland Plateau, separated from the main portion of the plateau by the Tennessee River and Sequatchie Valley.  The average elevation on Sand Mountain is around 1500 ft above sea level, compared to about 650 ft in the surrounding area.  This elevation leads to its having the coolest climate in the state of Alabama.  The largest city on Sand Mountain is Albertville, in Marshall County.  As of the 2010 census, the population of the city was 21,160.

Mid Severn Sandstone Plateau: The Mid Severn Sandstone Plateau is a rural landscape and one of the natural regions of central England, straddling the border between the counties of Shropshire and Staffordshire.  It stretches from the western fringes of the Birmingham conurbation to Telford in the north and Kidderminster in the south.  The major feature of the plateau is the valley of the River Severn, which cuts through it from north to south.  It consists of Permian and Triassic-age New Red Sandstone getting older as one goes west until one reaches Silurian and Carboniferous-age siltstones and coals west of the river.

Harischandra Range: The Harischandra Range is a group of hills in the state of Maharashtra, India.  It lies in the northwestern region of the Deccan Plateau, between the Godavari and the Bhima rivers.  These are low-lying hills with an average elevation of about 600 metres, and they lose elevation in the southeastern direction.  The Kalsubai is the highest peak.  The Harishchandragad is another important peak.  The range is thought to have been formed as a result of the downward erosion of the basaltic Deccan Plateau by the Godavari and Bhima rivers.  In the northwest, the range merges with the Western Ghats.

Adamawa Plateau: The Adamawa Plateau (French: Massif de l'Adamaoua ) is a plateau region in central Africa stretching from south-eastern Nigeria through north-central Cameroon (Adamawa and North Provinces) to the Central African Republic.  The plateau was named after Fulani Muslim leader Modibo Adama.  The part of the plateau that lies in Nigeria is more popularly known as Gotel Mountains.  The Adamawa Plateau is the source of many waterways, including the Benue River.  It is important for its deposits of bauxite.  The average elevation is about 3,300 feet (1,000 meters), but elevations can reach as high as 8,700 feet (2,650 meters).  The vegetation is mostly savanna, and is sparsely populated.  Cattle raising is the main occupation in the area.

Biu Plateau: The Biu Plateau is a highland area in Northeastern Nigeria containing many recently extinct volcanoes.  It covers about 5200 km2 and has an average elevation of 700 m .  The plateau lies between the Upper Benue Basin to the south and the Chad Basin to the north.  High points are Wade Hill at 775 m above sea level and Wiga Hill, at well over 800 m .  The plateau is the source of many tributaries of the Gongola River, which have cut deep gorges.  To the north the plateau slopes gently to the Bauchi plains and the Chad Basin.

Kwahu Plateau: The Kwahu Plateau is a 260 km long plateau in southern Ghana.  It consist of the uplifted southern edge of the Volta River Basin.  It forms the main watershed of Ghana, separating rivers in the Volta River system from rivers in the western half of Ghana which flows into the Atlantic Ocean(Birim,Pra, Ankobra).  The plateau has an average elevation of 1,500 feet and its highest point is Mount Akmawa at 2,586 feet.  The plateau is dissected by several valleys and is marked by tall peaks.  To the south it borders dense forest country, which it shields from the harmattan winds of the interior.  Cacao cultivation has been introduced in the west, through which traditional trade routes lead to the Atlantic; vegetable cultivation is stressed in the eastern sector.  The largest and most important towns on the Kwahu Plateau are Wenchi, Mampong, Mpraeso, and Abetifi.
