Canyoneer Constrychnine Canyon North Wash BLM, UT

Apr 11, 2021 — Constrychnine Canyon is one of the canyons in the popular Poison Spring area. It's not a favorite, really just seeming like a bunch of rappels through a chasm, but it does have some pretty highlights within the short narrows. Reaching the trailhead is possible by any vehicle. We started north along a social trail and continued past the head of Slideanide Canyon, and continuing through the desert toward the head of Constrychnine Canyon. A Class 2 option led into the head of the canyon and we started down the wide drainage. The first big rappel met us shortly after, which brought us off the rim and into more wash walking. The second big rappel led into Constrychnine Canyon's narrows. A third big rappel brought us deeper still. Walking through the narrows was mostly easy with just some boulders and light scrambling, but stemming and down-climbing was minimal. A fourth rappel was anchored off a chockstone and was shorter, and prettier, leading into a short section of the prettiest narrows for the canyon. A final rappel (short enough you may want to consider just sliding down it) led into the watercourse.

Once out of Constrychnine Canyon, continue north down the watercourse. We passed three side-canyons on the right as well as a small lush section with some trees. Past the third side-canyon is a ramp on the left. This was our exit. Easy slabs led to a Class 3 move aided by a small stack of rocks. A Class 3 move was also required to get off the slope and reach the rim, a slightly more difficult move. A social trail led back to the trailhead.
