* Cajas National Park has a surface area of 28,544 hectares and an elevation between 3,150 and 4,450 meters above sea level. Rock formations are from the Mesozoic era, where large volcanic phenomena begun and the Andean mountains lifted. Lake complexes come from the Quaternary era where glacier movements and formation began, and where the mammoth lived and man began its origin and development. During the glaciation period "u", u-shaped valleys formed just as the graded lakes in "boxes"(cajas). Trails treversing the park witness the presence of pre-colonial cultures and the Ingacarretero (The Royal Path of the Incas).*
