Wow Steve you are becoming either a mapping guru or crossed over to a complete mapping geek.
Humph! Yeah, I know. My obsession with maps began about the same time as my love for backpacking. I'd pore over a map and decide on a trip based on the terrain and trails (or lack thereof).
And this last JMT hike, I actually got lost for an hour -- partly because I didn't pay close attention to the maps. See the
trip report....I was afraid nobody would have any suggestions here...
