The rim-to-rim journey across the Grand Canyon is considered one of the quintessential hikes in North America—and for good reason. The North Kaibab and Bright Angel trails combine to exploit a rarified cross-canyon thoroughfare, one that harbors many delights for the experienced backpacker. Boasting one of our planet's most spectacular and accessible geologic cross-sections, Grand Canyon routinely draws geology buffs of all stripes.

This class will examine the canyon’s rich geological story, from ancient Precambrian metamorphic rocks to recent debris flows. Discussions will include the structural geology, stratigraphy, hydrology and formation theories as evidenced along this amazing 24-mile route. Roaring Springs, Ribbon Falls, Phantom Ranch and Plateau Point are but a few of the treasures awaiting those who take part in this moderate-intensity backpack. After being shuttled to the North Rim, the class will spend its first night at the North Rim Campground. During the precipitous descent into the canyon, participants hike from an aspen-clad forest to the banks of a desert stream in a few short hours. Nights are spent at Cottonwood, Bright Angel and Indian Garden Campgrounds respectively. The final day of class includes a 4.5-mile hike to the top via the Bright Angel Trail, each hiker traveling at his or her own pace.
