      • It spans over the West Coast of South America, rising in the North in Colombia and finishing in Chile and Argentina in the South.
    • Farming
      • The Andes are used for a variety of farming practices.
      • The best farming land is the valley floor,  however terraces are dug into the valley sides which makes farming in the harsh environment easier.

        • The nearby town of Cajamarca has grown from 30,000 to 300,000 since the mine opened.
    • Hydroelectric dam
      • The deep valleys and rivers of the valley make it ideal for hydroelectric power.
      • Snow melt fuses most of the water but this means HEP can be limited in winter.
      • In 2009, the El Latanal HEP plant began to generate electricity, involving a huge dam project over the Canete river costing $200m.
