You will have to check out Wilderness Medical Associates (WMA) and Wilderness Medical Institute (WMI) for courses. These 2 companies are the world leaders in wilderness medicine.

The Wilderness First Responder Course (WFR) is an 76-80 hr course over 8 days for generic outdoor activities (including boating, backpacking, rock climbing, etc.) There is only 1 "wilderness" level above that. It is a combination of EMT and WMT and takes 1 month to complete the 180 hr course. http://www.wildmed.com/Courses/EMT+WEMT_syllabus.htm http://www.nols.edu/wmi/courses/schedule.shtml#WEMT

Beyond that - you are getting into paramedic courses but they will be designed for the urban environment. "Wilderness medicine" is a relatively new discipline having only begun in the early 90's. If you need anything more than the training above - hire yourself a emergency room doctor!

I can vouch for the WMA WFR course having taken it in March - best money I ever spent on training. It gave me certification in Basic Life Support and CPR for adult/child/infant, 2-person support, automated external defibrillator (AED), oxygen administration, brief intro to endotracheal intubation, using the BP cuff and stethoscope, anaphylaxis workshop and the 6 specific wilderness medical protocols.
