Question: Frontal Cordillera extends in a north-south direction in the province that borders what country on the west?
Context: Tundzha Glacier (Lednik Tundzha \'led-nik 'tun-dzha\) is a glacier on Livingston Island in the South Shetland Islands, Antarctica situated east-southeast of Berkovitsa Glacier, west of Saedinenie Snowfield, northwest of Pimpirev Glacier, north of Kamchiya Glacier and east-northeast of Verila Glacier.  It is bounded by Snow Peak to the west, Teres Ridge to the east and the glacial divide between the Drake Passage and Bransfield Strait to the south.  The glacier extends 14 km in east-west direction and 4.5 km in the north-south direction, and drains northwards into Hero Bay between Avitohol Point and Siddins Point. The geology of Bolivia comprises a variety of different lithologies as well as tectonic and sedimentary environments.  On a synoptic scale, geological units coincide with topographical units.  The country is divided into a mountainous western area affected by the subduction processes in the Pacific and an eastern lowlands of stable platforms and shields.  The Bolivian Andes is divided into three main ranges; these are from west to east: the Cordillera Occidental that makes up the border to Chile and host several active volcanoes and geothermal areas, Cordillera Central (in some contexts also called Cordillera Oriental) once extensively mined for silver and tin and the relatively low Cordillera Oriental that rather than being a range by its own is the eastern continuation of the Central Cordillera as a fold and thrust belt.  Between the Occidental and Central Cordillera the approximately 3,750-meter-high Altiplano high plateau extends.  This basin hosts several freshwater lakes, including Lake Titicaca as well as salt-covered dry lakes that bring testimony of past climate changes and lake cycles.  The eastern lowlands and sub-Andean zone in Santa Cruz, Chuquisaca, and Tarija Departments was once an old Paleozoic sedimentary basin that hosts valuable hydrocarbon reserves.  Further east close to the border with Brazil lies the Guaporé Shield, made up of stable Precambrian crystalline rock. Teteven Glacier (Lednik Teteven \'led-nik 'te-te-ven\) is a glacier on Greenwich Island in the South Shetland Islands, Antarctica situated east of Yakoruda Glacier, west of Quito Glacier, northwest of Traub Glacier and north of Murgash Glacier.  It extends 6.5 km in east-west direction and 3.8 km in north-south direction, and drains the north slopes of Dryanovo Heights into the Drake Passage in Haskovo Cove and Skaptopara Cove between Miletich Point and the ice-free area at Agüedo Point. San Juan (] ) is a province of Argentina, located in the western part of the country.  Neighbouring provinces are, moving clockwise from the north, La Rioja, San Luis and Mendoza.  It borders with Chile at the west. The Cordillera de Talinay is a mountain range situated in the Coquimbo Region of Chile.  The range consists of a series of hills and foothills spreading more than 40 km in a north-south direction from the coast, but which descend to meet the Limari river as it crosses Chile's Intermediate Depression ("Depresión Intermedia" or "Valle Longitudinal" (longitudinal valley)). Frontal Cordillera (Spanish: "Cordillera Frontal" ) is a mountain range in western Argentina that forms part of the Andes.  It extends in a north-south direction in the provinces of La Rioja, San Juan and Mendoza.  To the west of the Frontal Cordillera lies the Principal Cordillera that makes up the Argentina–Chile border and the continental divide.  "Cordillera" means "mountain range" in Spanish. The B1 is one of the most important roads in Namibia, passing through the centre of the country in a north-south direction.  It connects Noordoewer on the South African border with Oshikango in the north on the Angolan border.  Important cities it passes through in a North-South direction include Oshikango, Ondangwa, Tsumeb, Otavi, Otjiwarongo, Okahandja, Windhoek, Rehoboth, Mariental, Keetmanshoop and Noordoewer. Yakoruda Glacier (Lednik Yakoruda \'led-nik ya-ko-'ru-da\) is a glacier on the west slopes of Dryanovo Heights, Greenwich Island in the South Shetland Islands, Antarctica situated west of Teteven Glacier and northwest of Murgash Glacier.  It extends 3.5 km in north-south direction and 2.5 km in east-west direction, is bounded by Greaves Peak, Hrabar Nunatak and Crutch Peak to the north, Lloyd Hill to the east and Kerseblept Nunatak to the south, and drains westwards into Berende Cove, McFarlane Strait. Tarnovo Ice Piedmont (Lednik Tarnovo \'led-nik 't&r-no-vo\) on Rozhen Peninsula, Livingston Island in the South Shetland Islands, Antarctica is situated southeast of Charity Glacier and west-southwest of Prespa Glacier.  It extends 3.5 km in east-west direction and 2.5 km in north-south direction, is bounded to the west by Veleka Ridge, to the north by Arda Peak, Gerov Pass and Shumen Peak, and to the east by Yambol Peak, and flows southeastwards into Bransfield Strait east of Botev Point and west of Gela Point. The Caldera Lauca is a caldera in the Arica y Parinacota Region of Chile.  It is located in the Cordillera Occidental, in the valley of the Lauca River.  The elliptic caldera has an east-west extension of 23 km and 50 km in north-south direction, buried beneath the late Miocene Vilañuñumani-Tejene volcanic complex in the north and ending at Chucal in the south.  The 21 mya Oxaya Ignimbrite originates in the caldera.  The eastern border of the caldera is buried beneath younger ignimbrites and deposits but is located east of the Guallatiri volcano.  An Oligocene fault marks the western edge of the caldera.
