I believe John Huggins found one when we did the annual AT event because he added it to all his RF link maps.  It appears to be pretty high resolution.

The original APRSdos also had the complete trail, though I hand made it back in the 90's and so it is not high resolution.  Lets see if John has his file?

What I wouild do, is take all the points on the trail (filering down to about a point evrey mile) and then run each point past the Echolink file.  Keeping the minimum distance Echolink node for each point.

That would be about 2000 entries.  Then filtering out all the dupes for the minimum distances.  Bingo. Done.

Do the same for all digipeaters.
The for all IGates...

Then that would make a nice handy data file for a h iker.
