The course was a multidisciplinary study of the ecology, geomorphology and management of the San Juan River. Comprised of upper-division undergraduate students and graduate students, the course brought together students from a range of biological and physical sciences to address the geology, ecology, and management of the San Juan River watershed. The course involved classroom instruction and literature review papers written by the graduate students on specific topics related to the San Juan River watershed. It culminated with a seven-day rafting trip on the San Juan River during which students collected and analyzed field data.
