Maybe this will be useful to someone here. I came across an organization that accredits outdoor education programs -- The Association for Experiential Education. They have lists of accredited programs and colleges
http://www.aee.org/accreditation/programs
and lists of job openings (instructors, etc.)

An example of a job is "Adjunct Faculty - Winter Expedition Field Instructor" in the Adirondacks, which I thought was kind of neat, but not lucrative.
