Jason Pease in Constrychnine

Poison Spring Canyon
Technical Canyoneering

          Constrychnine (Constrict + Strychnine) is a tantalizing canyon with long charming rappels. The beauty of this canyon is spectacular; the narrows are deep, tight, dramatic and fun. The technical section contains an excellent chamber buried deep in the bowels of the slot canyon. This is a fun and technically challenging adventure.
