Apuseni Mountains in the context of "Transylvania"

The Someșul Mic (Little Someș, Hungarian: Kis-Szamos) is a river in north-western Romania (Cluj County). At its confluence with the Someșul Mare in Mica, the Someș is formed. Its total length is 178 km (111 mi), and its drainage basin area is 3,773 km (1,457 sq mi). It is formed at the confluence of two headwaters, Someșul Cald ("Warm Someș") and Someșul Rece ("Cold Someș"), that originate in the Apuseni Mountains. From the confluence, in Gilău, the Someșul Mic flows east and north through Cluj-Napoca, Apahida and Gherla, until it meets the Someșul Mare in Dej.

Crișana (Romanian: Crișana, Hungarian: Körösvidék, German: Kreischgebiet) is a geographical and historical region of Romania named after the Criș (Körös) River and its three tributaries: the Crișul Alb, Crișul Negru, and Crișul Repede. In Romania, the term is sometimes extended to include areas beyond the border, in Hungary; in this interpretation, the region is bounded to the east by the Apuseni Mountains, to the south by the Mureș River, to the north by the Someș River, and to the west by the Tisza River, the Romanian-Hungarian border cutting it in two. However, in Hungary, the area between the Tisza River and the Romanian border is usually known as Tiszántúl.

Roșia Montană (Romanian pronunciation: [ˈroʃi.a monˈtanə], "Roșia of the Mountains"; Latin: Alburnus Maior; Hungarian: Verespatak, [ˈvɛrɛʃpɒtɒk]; German: Goldbach, Rotseifen) is a commune of Alba County in the Apuseni Mountains of western Transylvania, Romania. It is located in the Valea Roșiei, through which the small river Roșia Montană flows. The commune is composed of sixteen villages: Bălmoșești, Blidești, Bunta, Cărpiniș (Abrudkerpenyes), Coasta Henții, Corna (Szarvaspatak), Curături, Dăroaia, Gârda-Bărbulești, Gura Roșiei (Verespataktorka), Iacobești, Ignățești, Roșia Montană, Șoal, Țarina, and Vârtop (Vartop).

The rich mineral resources of the area have been exploited since Roman times or before. The state-run gold mine closed in late 2006 in advance of Romania's accession to the European Union. Gabriel Resources of Canada plan to open a new mine. This has caused controversy on one hand over the extent to which remains of Roman mining would be preserved and over fears of a repeat of the cyanide pollution at Baia Mare and on the other, over the benefits that mining would bring to this poor and underdeveloped part of the country.

Oradea (UK: /ɒˈrɑːdiə/, US: /ɔːˈr-, -djɑː/, Romanian: [oˈrade̯a]; Hungarian: Nagyvárad [ˈnɒɟvaːrɒd]; German: Großwardein [ˌɡʁoːsvaʁˈdaɪn]) is the capital of the Crișana region in Romania. It serves as the administrative centre of Bihor County. The city is situated on both banks of the Crișul Repede River.

As of 2021, Oradea is Romania's ninth most populous city. It is located approximately 10 km (6.2 mi) from the Hungarian border. The municipality covers 11,556 hectares (28,560 acres) and lies between the Apuseni Mountains and the Crișana-Banat plain.

The Someș (Romanian pronunciation: [ˈsomeʃ]) or Szamos (German: Somesch or Samosch) is a left tributary of the Tisza in Hungary and Romania. It has a length of 415 km (258 mi) (including its source river Someșul Mare), of which 50 km are in Hungary. The Someș is the fifth largest river by length and volume in Romania. The hydrographic basin forms by the confluence at Mica, a commune about 4 km upstream of Dej, of Someșul Mare and Someșul Mic rivers. Someșul Mic (formed by the confluence of Someșul Rece with Someșul Cald) originates in the Apuseni Mountains, and Someșul Mare springs from the Rodna Mountains.

Someșul Mare has a length of 130 km and an area of 5,033 km and a slight asymmetry in favor of the left side of the basin. For the entire basin of Someș, the asymmetry on left becomes pronounced between Dej and Ardusat to change in the opposite direction after receiving the Lăpuș on the right side. The valley of Someșul Mare has much auriferous alluvium that, until the early 20th century, were brought to the surface using traditional tools. Specialists say that in the Someșul Mare were found grains of gold of 21 carats.

The Trascău Mountains (Romanian: Munții Trascăului) are located in the Apuseni mountain range of the Western Romanian Carpathians, in Romania.

The Trascău Mountains are crossed by the picturesque Arieș River valley. The highest elevation in the massif is Dâmbău Peak, at 1,369 metres (4,491 ft).

The Körös (Hungarian pronunciation: [ˈkørøʃ]) or Criș (Romanian pronunciation: ['kriʃ]) (German: Kreisch) is a river in eastern Hungary and western Romania. Its length is 128.6 km (79.9 mi) from the confluence of its two source rivers Fehér-Körös (Crișul Alb) and Fekete-Körös (Crișul Negru) to its outflow into the Tisza. Its drainage basin area is 27,537 km (10,632 sq mi). It has three source rivers, all with their origin in the Apuseni Mountains in Transylvania, Romania: Crișul Alb (Fehér-Körös), Crișul Negru (Fekete-Körös) and Crișul Repede (Sebes-Körös). The confluence of the rivers Fehér-Körös (Crișul Alb) and Fekete-Körös (Crișul Negru) is near the town Gyula. The Körös downstream from Gyula is also called the Kettős-Körös (Hungarian for "double Körös"). 37.3 km further downstream, near Gyomaendrőd, the Sebes-Körös (Crișul Repede) joins the Körös/Criș. The section downstream from Gyomaendrőd is also called the Hármas-Körös (Hungarian for "triple Körös"). The Körös flows into the Tisza River near Csongrád in Csongrád county.

It was known in antiquity as the "Chrysus", Crisus, Crisia, Grisia, or Gerasus.

The Crișul Alb (Romanian), (Hungarian: Fehér-Körös) is a river in western Romania, in the historical region of Transylvania, and in south-eastern Hungary (Békés County).

Its source is in the southern Apuseni Mountains (Romanian: Munții Apuseni) of Romania. It flows through the towns of Brad, Ineu, Chișineu-Criș in Romania, and Gyula in Hungary. Crossing the border of Hungary, the river, now called Fehér-Körös, joins the Fekete-Körös (Crișul Negru) a few kilometres north from Gyula to form the river Körös (Criș), which ultimately flows into the Danube. In Romania, its length is 234 km (145 mi), and its basin size is 4,240 km (1,640 sq mi).
