Canyons are inherently risky. Flash floods occur without notice on sunny days. Technical skills & surrounding topography knowledge required yet does not eliminate risk.
Crack Addict Canyon is a 1.25 mile one way canyon trip with a 1200 ft drop in elevation. Located 14 miles south-southwest of Flagstaff Arizona. May and June are the best months to enjoy this activity. This hike involes off trail navigation. Review triplogs, photos and the route to understand the terrain before heading out.
An adventurous crack fault canyon with 8-10 rappels up to 180ft that's great to do when you're in the area and want to stay mostly dry or avoid the monsoons by doing a canyon without much flash flood potential. From the car park, head north down into the canyon. When you're thru the technical section, you can either head down Sterling Canyon to another vehicle left along 89A or head up Sterling Canyon to loop back along 535A to your vehicle.
