Each adult field course is rated according to the level of physical activity required.  We practice “Leave No Trace” ethics; however, all levels may involve some off-trail travel through brush and/or uneven terrain.  Although Institute staff and instructors exercise every caution to prevent mishaps, students must assume full responsibility for their own safety.  We ask that you evaluate your own physical condition before making a commitment to participate in any of our programs. We require that you sign a liability waiver at the start of each class.
