Backpacker mappers covered 3,100 miles in the Continental Divide Trail Project.
209 readers were dispatched to GPS map the CDT, including Map Editor, Kris Wagner (far right).
Backpacker provided 50 teams with GPS units, training, and miles of trail to map.
Many sections of the CDT are poorly marked.
Dramatic scenery peppered the trail from Canada to Mexico.
From flat to steep, teams produced the most accurate data to date on the CDT.
One of the comforts of the trail.
3,000 people applied to be part of the team. Entries came from all over.
The geology of the trail was just as varied as the terrain. Here a hot spring bubbles up.
Team 40 was charged with mapping the trail from Idaho's to Montana's Bannock Pass.
Panoramic vistas aren't a bad place to hang up your trekking poles for the night on the CDT.
Sunsets from mountain to desert provided the perfect night cap.
From lush forests to rocky crags teams had to contend with flats, as well as steeps.
Although it wasn't easy, mappers created lifelong friendships...and came back with incredible tales.
Not to mention a boatload of pretty amazing photos.
