The Andes, Andes Mountains or Andean Mountain Range are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is 8,900 km (5,500 mi) long and 200 to 700 km wide and has an average height of about 4,000 m (13,000 ft). The Andes extend from south to north through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela.

Eliseo Víctor Mouriño Oyarbide was an Argentine footballer. He began his career at Club Atlético Banfield before moving to join Boca Juniors with whom he won an Argentine league title in 1954. He played as a holding midfielder for the early part of his career before converting to centre-back and was part of the Argentina squad at the 1958 FIFA World Cup. He died in a plane crash in 1961.
