I know you have a very AMC-centric way of thinking about everything and I'm sure their programs are fantastic but I don't think the issue is lack of resources available to hikers. It is no desire to gather the information. If people won't do some basic, free research online I don't think a $230, 3 Day AMC Map and Compass workshop is going to be the answer. AMC, REI and many others offer these courses and have been for awhile. It isn't exactly a secret. I'm not sure how many people can afford to take a course like this, even if the content is outstanding. You can teach yourself these skills pretty easily with online tutorials and a little practice for $0 or the nominal cost of many outstanding books on the topic. That requires effort however....
Day Trip is correct (with bold emphasis added by me).
I'll come at the problem from two directions. I have self taught myself and practiced precision navigation methods beginning more than fifty years ago, beginning with what my father taught me as a young boy while hunting with him in backcountry areas he knew in great detail without question of where he ever was. I became an Air Force flight navigator and instructor/evaluator back in those pre-GPS Cold War dinosaur days when navigators were actually valued in aircraft. The mindset from air to ground navigation is not all that different as I learned to solo hike and backpack off trail in remote areas by myself. I learned and enjoyed applying my increasing knowledge of map and compass and thoughtful effort getting where ever I wanted to go in the woods.
Enter Boy Scout National Camp School and working with the NYSDEC and BSA to develop a training program for wannabe summer high adventure wilderness guides wishing employment with BSA Adirondack resident camps, leading week long paid treks for scouts and their adult leaders. For 30 years I worked as an instructor for candidate guides during the annual 8-day guide training program. My students were typically college age with varying levels of previous experience and skills in the outdoors and with BSA. Some had innate impressive skill and ability, others not so much. Keeping in mind that they would be responsible for safely guiding children in the woods, certification to work as a trek leader guide is not guaranteed. Out of a typical class of up to 25 trek leader students, two or three failures resulting in non employment is not uncommon. After the introduction of GPS and especially cell phones, attitudes and skills changed significantly. With my specialty of land navigation, students lucky enough to get me as their woodland instructor are in for a good challenge of off-trail backcountry navigation trials using map and compass only, no GPS and no cell phone allowed. I have failed students for cheating with a sneak peek at a hidden GPS, or for demonstrating no aptitude of learning how to navigate when all the tools and navigation clues were right in front of them in plain sight. I would happily provide separate basic GPS instruction later, but not during the core backcountry navigation skills development.
Simultaneously spending several years as a SAR volunteer and then certification by NYSDEC as a SAR crew boss. I was eventually recruited by NYS Homeland Security to periodically teach a formal land navigation class to state law enforcement, fire, EMS, and SAR team members. The program course was initially developed by recently returned from war zone military members as my co-instructors. i inserted much of my own methodology. Many of our more seasoned students indicated they had prior military navigation experience, although when questioned most indicated they were "a little rusty", a severe understatement in many cases. The course was at first advertised as including GPS training, but doing that just did not work out well. Even though the state provided a basic low level GPS unit to train on, every student had brought their own individual GPS unit and would approach an instructor with questions about how to set it up an read it. Although every unit in the end provides the same answer, we instructors could not be an expert in exact operation of all of the dozens of different commercial models of GPS units. Doing so simply took too much time from learning other needed course work skills. So we dropped GPS segment from the syllabus, focusing instead on traditional map and compass and terrain association.
To this day, although especially for SAR where GPS is a necessary tool, I practice GPS skill during SAR incidents, when I recreationally head into the woods myself, it is map and compass only as my preferred method of enjoying my travels. it is often said that land navigation is a perishable skill without frequent practiced usage, and I am determined to not let my traditional map and compass navigation skills get stale.
Here is just one example:
