It's on again! 
Float the Colorado River with ASU geologists!

Raft the Grand Canyon with ASU geologists guiding you through the last 500 million years of Earth's history!

Confirmed dates—May 29 through June 5, 2021

Due to COVID-19 restrictions, please let us know if you are interested in joining this trip in May 2021. We are setting up a list of potential travelers so we can be ready when it is safe to travel freely again. Email Julie Russ at jruss@asu.edu to be added to the travelers list.

One of those trips of a lifetime—floating and splashing down the Colorado River! Sleeping under the stars (or in a tent if you wish!). Looking up at towering rock cliffs during the day and a star-filled sky at night.

IHO has secured two boats for a week-long trip down the Colorado River guided by two ASU geologists—Chris Campisano PhD and Ramon Arrowsmith, PhD.

The trip will begin at Lee's Ferry and travel on quiet, motorized rafts from mile 0 to mile 187, where you will helicopter out to return to your car at Lee’s Ferry or catch a small plane back to the airport in Las Vegas.

You will be roughing it—but not totally! Sleep in tents or on cots under the stars, eat three freshly prepared meals each day under a bright blue Arizona sky, and travel down the river as we go back two billion years of Earth's history, revealed by our guides—ASU scientists with expertise in geology and the deep history of the Earth.

Rafting the grand canyon

This is an amazing bucket list experience and includes not only some of the biggest, most famous rapids (negotiated expertly by long-time river operators Hatch River Expeditions) but also the awesome beauty of the Canyon itself!

The price for the trip is $3,317 per person—the cost to Hatch River Expeditions—plus $123 per person payable to ASU to support two ASU geologists as guides for a total of $3,440 per person. 

The Institute of Human Origins organizes these trips as friend and fund-raising ventures, and so requests a donation of $500 per person payable to the ASU Foundation to benefit research, student scholarships, and public outreach for the ASU Institute of Human Origins through the ASU Foundation for a New American University.

Please contact Julie Russ at jruss@asu.edu or 480-727-6571 if you are interested! Canyon reservations are difficult to secure and spaces for this bucket list adventure will go fast! 

We hope you will join us on this incredible adventure!

Charitable Donation

IHO organizes these trips as fund- and friend-raising events. IHO's trips programs help to suport IHO research, student scholarships, and public outreach. We also hope that if you just like to travel, you will feel great about learning and supporting science at the same time!

A charitable contribution of $500 per adult* payable to the ASU Foundation is requested to support IHO student scholarships, field and laboratory research, and public outreach. A separate letter with information about this request will be provided to confirmed travelers.

Your gift of $500 per person will be deposited with the ASU Foundation for a New American University, a separate nonprofit organization that exists to support ASU. Gifts in support of ASU are subject to foundation policies and fees. Please consult with your tax advisor regarding the deductibility of charitable contributions (IFAS 30002491).

Expert guides

Two ASU geologists—IHO Research Associate Chris Campisano and School of Earth and Space Exploration Professor Ramon Arrowsmith—will lead the trip to engage you in understanding the deep geological history of the Grand Canyon.

Campisano is an expert in ancient landscapes and evolution, and Arrowsmith studies geological faults, topography, and the geology of earthquakes. Both scientists have rafted the canyon in the past.

In addition, Hatch provides seasoned river runners to guide the boats and daily logistics and also provide a wealth of knowledge about the river and canyon.

Experienced river runners

The river rafting company is Hatch River Expeditions (link is external), a family-owned, long-time provider on the Colorado River. On the company’s website is a terrific FAQ page (link is external) that covers many questions that you may have!

Email Julie Russ at jruss@asu.edu if you are interested in joining this exciting adventure!

Reservations will be managed on a first-come, first-served basis. Deposits and final payments will be made directly to Hatch River Expeditions. The $123 fee to support the two ASU geologists will be paid to the ASU Institute of Human Origins for remittance to Hatch (due to National Park Service rules, Hatch is not allowed to collect additional funds above the cost of the trip).

In your confirmation, please include the names of people in your group (indicate any minors with ages), addresses, mobile phone number, and email addresses. This information will be needed by Hatch River Expeditions to provide you with additional information and invoice you for the trip.

Note: Hatch’s cancellation policy includes forfeiture of the deposit in the event of any cancellation. If I receive enough responses to fill the reservation, I will begin a wait list. I will let you know if you are on the wait list.

This truly is a bucket-list trip for many people, and we are so excited to be able to offer this adventure to IHO friends!
