There is so much to safely practice on at Stoney Point if you have a good book and a rope and some very basic gear. For canyon-oriented stuff, there are many bolted anchors on top of high but low angle slabs to practice rappelling on. Plenty to do on steep or overhanging rock as well. It's a good place to practice. I'm likely going to go out there next weekend with my kids; I want to get them up to speed for easy Utah canyons this summer as well as practice a few things myself (passing knots on rappel and a few rope climbing techniques as well as lowering an injured partner scenarios).
I can place climbing anchors (used to lead easy stuff) but have yet to do anything very serious while canyoneering. Everything I've done so far, which isn't much, has only involved wrapping trees or boulders with webbing or simply replacing slings on bolt
