I have taken the time to input EVERY waypoint for every trail in Charles Wells' Moab book and BOTH of his Colorado books.
They are in the format that Garmin Mapsource uses so I can give anyone the file if they desire. I spoke to Charles before posting this and both he and I want to stress that the GPS data that's in the Moab book is about 10 years old (NEW UPDATED BOOK ON THE WAY EARLY 2008) when GPS's weren't that accurate/reliable. While I did my best to input and proof read the data accurately I can't take resposibility for either the accuracy of the positioning or the data itself.
The Colorado books coords are right on it seems. I have done a few trail using the coordinates and they were pretty damn accurate. It's amazing how things have changed so much over a few years.
EDIT: You don't have to email me for them now. They are avaliable for download HERE (further down the thread). Thanks Eric for setting that up. Each book has it's own file. There are 403 points in the South Colorado book, 229 in the North Colorado book, 429 in the original Moab book, and 420 in the 2nd Edition Moab book.
EDIT 02/08: CHARLES HAS PUBLISHED A 2ND EDITION MOAB BOOK. THOSE FILES SHOULD BE AVALIALBE TOO. I POSTED A QUICK THREAD HERE ABOUT THAT BOOK.
In addition to retailers, Charles sells his books directly from his site at www.funtreks.com. One thing he offers that you won't get in a retail store is sprial bindings for I believe an additional $3. Giddy-up!
