River Rafting Through the Grand Canyon
August 18–23, 2021

President's Circle Travel Program with Michael Lamb
Calling all thrill seekers and outdoor enthusiasts!
August 17–23, 2021—SOLD OUT
See the Grand Canyon, one of the seven natural wonders of the world, from a unique vantage as you journey 188 miles down the Colorado River. During the day, traverse both calm waters and Class V rapids on motorized rafts, go on hikes to see up close some of the Grand Canyon's stunning rock formations, and rest in the area's tranquil waters. Then, spend your evenings relaxing at your campsite as you gaze at the stars and enjoy dinners prepared specially for you. Throughout your adventure, Caltech Professor of Geology Michael Lamb will show you why the Grand Canyon, with its biodiversity, rare ecosystems, and steep-walled canyons, is considered a living classroom. This travel program, organized by Western River Expeditions, enables you to see a part of the Grand Canyon not often visited by tourists.
Only 25 spots are available for this trip, and we encourage you to register as soon as possible. President's Circle members may bring a total of four guests who must be at least 12 years old.

Faculty Leader

Michael Lamb is a professor of geology at Caltech. He studies the dynamics of landscapes on Earth and other planets through the mechanics of erosion, transport, and deposition of sediment. Among his areas of active research are canyon formation by rivers, post-wildfire debris flows, the response of river deltas to sea-level rise, and ancient rivers on Mars.
Professor Lamb was awarded the Luna B. Leopold Award and the James B. Macelwane Medal by the American Geophysical Union. He graduated from the University of Minnesota with BS degrees in geology and geophysics. He received an MS in oceanography from the University of Washington and a PhD in earth and planetary sciences from the University of California, Berkeley. This will be Professor Lamb's third trip to the Grand Canyon.
