Mike Wagner posted this adventurous out & back route:
Lower Grand Gulch - Collins Spring to the San Juan River. ~32.1 miles, ~+7,301', 8h 7m elapsed time.
Mission accomplished! Though not a perfect effort. I got lost twice (as seen on Strava). I didn't drink nearly enough water. The route through the canyon is vague to non-existent. Quicksand, cactus, crypto, strong winds, constant route finding, and when I started it was 35 degrees but when I finished it was 85 degrees.
In my opinion, this was one helluva effort. If I could hope for one outcome from this experience it's that someone else takes on the Lower Grand Gulch. It's a true southwest challenge. Not for the faint of heart or unprepared.

(Note that Mike shortcut the route some when he got lost and exited the canyon proper. The route seems to be closer to 42 miles.)
