Besides me, your fearless and ultra-experienced professor, we are very fortunate to have the following three people as teaching assistants/outdoor experts/helpers on this trip: Steve Nerney, Keith Reineke, and Rob Rounds (in alphabetical order - no way to use a hierarchy here). They will help with logistics, preparation, general advice, group leading, map interpretation, wilderness first aid, nutrition, decision-making, and advising me. Again, we are really lucky to have them on the trip - it will make our time less stressful and more enjoyable. Please read over the blurbs about hiking rim to rim at the G. Canyon. If anyone knows right now that they are not going to attempt this 27 mile hike in extreme heat with a 20-50 lb back pack, let me know. It will help with planning how we do this hike.
