Canyons are inherently risky. Flash floods occur without notice on sunny days. Technical skills & surrounding topography knowledge required yet does not eliminate risk.
amAZing loop starting from the Eminence Break TH and following that geological fault NE towards Tatahatso Canyon and dropping into a cairned steep ravine down in the middle canyon. After much down climbing & boulder hopping, you'll eventually reach the challenging lower narrows with over a handful of awkward rappels up to 75ft. Once you reach the river, be prepared to spend the night and navigate down the river 7 miles back to the Eminence Break trail. I highly recommend doing the nearby Tatahosa Canyon that afternoon and hiking out that steep exposed trail the next shady morning. =)
