Four Pass Loop Hiking Guide: GPX files
Kraig Adams, kraigadams.com

These are my own GPS recordings of my four days on the Four Pass Loop in the
Maroon Bells-Snowmass Wilderness, Colorado, September 25 to 28, 2021. I
started and finished at the Maroon-Snowmass Trailhead on the Snowmass side
and went over the four passes counterclockwise from Snowmass Lake. They show the way
I actually walked, with a point every 15 m (50 ft) or so. All timestamps have
been removed.

four-pass-loop-full-route.gpx   All four days in one file, plus waypoints
                           for the trailhead, the passes, the lakes and my

stats.json                 The numbers for each day.

Total for the four days: 43.7 mi (70.4 km), about 9,680 ft (2,950 m) of
climbing and the same down. The distances are those of my full recordings;
apps measure these thinned files a little shorter.

My campsites are marked so you can see where I stopped in 2021. Since 2023
the area needs an overnight permit and has camping rules (see the guide):
camp where your permit and the rules allow, not just where I did.
