About Us

Who we are

A team that loves to Dream

We are a multifaceted group of adventurers and scientists led by Expedition leader and biologist Phil Buck that strives to add a new understanding to the body of scientific  knowledge.  We produce films, write books and articles as well as publish photos about our expeditions. We have an educational program including this web page where schools and universities are able to follow along on the expeditions in real-time while the adventures are taking place. 

What we do

Adventures to the end of the wolrd

Today we live in a world where everything is disposable and replaceable.  Traditional Andean philosophies and cultures align with concepts of harmony and balance in nature. They teach us that human beings and mother earth are an interconnected whole.

The Viracocha III raft is not only about crossing the ocean for the purpose of testing the capacity of ancestral vessels, but also seeks to convey a message about the conservation of the marine environment and its importance in our ecosystem.

Researching pollution in the Pacific Ocean and how it affects the marine world will raise awareness of the magnitude of the damage we are causing to our own home.  

We are spreading this message to new generations and communities through environmental education programs, social media presence and a documentary.

History of Buck Expeditions


In The Wake of Lewis and Clark- 1987 

Canoe Expedition - A 5,000 mile journey across the United States following the route of Lewis and Clark. This was longest continuous tandem canoe trip ever completed, spanning seven months from Astoria, Oregon to Washington, DC

23 Peaks Expedition -1988- 1998

Phil Buck became the first person to climb the highest mountain in every nation in North, Central and South America. 

The Viracocha Expedition 1998- 2000

Inspired by the world famous explorer Thor Heyerdahl before his death, Phil Buck plan was to support the theory that it was possible that the ancient South American civilizations, could cross vast areas of the Pacific Ocean in old-style boats and that reed rafts were viable nautical vessels, possibly being a key factor of human migration and the spread of civilization.The first voyage was a journey from Arica, Chile to Easter Island, Polynesia in 44 days in 2000. It was the first primitive vessel of any kind to reach the island in modern times.


The Viracocha II Expedition 2003

In March 2003, a team of eight men led once again by Phil Buck, set sail from Viña del Mar, Chile aboard a new reed raft, the Viracocha II in an attempt to sail 10,000 nautical miles across the Pacific Ocean to Cairns, Australia, via Easter island and other islands beyond. Unfortunately, the raft was severely damaged during the launch and failed to test the its full potential of the raft as it only could reach Easter Island for the second time.


School Presentations

Teachers and students are able to travel with the explorers through experiencing the exciting adventures while it is taking place and at the same time learning about South American Cultures and Pacific Cultures, their ancestral traditions and ancient wisdom, which is a cornerstone of integration of nations for peace and respect for nature.

Building The Viracocha III Reed Raft 

Fourteen years later, with many of the same crew and including women for the first time, the Viracocha raft III  will navigate across the entire Pacific Ocean from Arica, Chile to Sydney, Australia on an epic journey of  approximately six months commencing in April of 2018, covering approximately 10,000 nautical miles.It is intended to demonstrate the enormous distances that these types of rafts could have sailed in ancient times. It will also help to preserve and promote the Andean and South American culture for the rest of the world to observe while inspiring future generations.

Open Air Museum 

We have opened two separate open air museums for the Viracocha III in the two construction locations in La Paz, Bolivia and Arica, Chile. We have welcomed presidents, ambassadors, chancellors, musical groups, government officials, universities, schools, public organizations and the general public. Crew members have given tours featuring photos and videos of our past reed raft expeditions and culminates with a tour of the vessel on land.
