iI have somewhere in the area of more than 300 USGS topographic maps, many that I inherited from a disbanded SAR team, others and duplicates I personally bought when they ran $4.50-$5 or less (now $15 or more). Mostly of the Adirondacks and adjacent areas of NY State. A few are from other states where I have been. When a SAR incident call-out comes, I can usually pull out the exact map that covers the area. Unfortunately, I feel true traditional land navigation (M&C) is becoming a lost art, as the NYSDEC rangers have even virtually completely ditched hand held GPS units and instead adopted Caltopo as the current default and the tiny cell phone display that it provides. It is assumed that everyone has and knows how to use the app in detail on their personal cell phone that “everyone” has or must have. I come from the time when a ranger would hand me a printed copy map of the area of search interest, and tell me to take my team to complete our assignment in “Block B” as was marked on the map. Map and compass accurately navigated me there and kept me there until that assignment is complete. Later when hand held GPS units came into play, they were handy, but still knowledge of the map and point plotting was required to get any use out of them. As a retired USAF navigator from the 1970's and 80's, I am certainly a dinosaur, since with rare specialized exceptions the USAF does not routinely train or use inflight navigators any more. Air navigation turns out to be not much different from land navigation in mental thought process and attitude, it's just a bit noisier.
