Sarah Krakoff, a professor at the University of Colorado Law School, is sending her students down river. Literally.

She and the 19 students in her natural resources class will brave the rapids on a two-week rafting excursion down the Colorado River and through the Grand Canyon—a first-of-its kind trip designed to explore water law and related legal issues on the ground (or on the water, as it were.) Krakoff has been contemplating the trip for more than a decade after rafting the river twice and using her photos to illustrate classroom discussions. The inaugural trip comes after two years of intense planning by Krakoff and extensive fundraising efforts by students to pay the portion of the $4,000 per-person cost not covered by the university. The group will cover 226 miles of the famed Colorado River, pushing off at Lees Ferry, upstream of the Grand Canyon, on May 15.
