Kantuta Expeditions
The Kantuta expeditions were two separate Pacific Ocean expeditions on balsa rafts led by the Czech explorer and adventurer Eduard Ingriš in 1955 and 1959, inspired by Thor Heyerdahl's Kon-Tiki expedition. The goal of Ingriš's Kantuta expeditions was to repeat the success of the Kon-Tiki and confirm Heyerdahl's theory about the migration of early South Americans to Polynesia.
