From Tortilla TH, walk south on FR213 and drop into the 2nd or 3rd side drainage on the east side. The 4th thru 8th drainages will put you into Minnow Canyon. This canyon has loads of bushwhacking thru catclaw, mesquite, and cactus with some light down climbing before you soon arrive at a major 140-160ft drop with 2 shinny bolts to run some webbing thru. I'm guessing you'd need about 50-60ft of webbing just so you have a clean rope pull since the bolts are back and around a bend. There's also a second drop below this one that's 100-120ft that has some large boulders you can anchor from. You should have a shuttle setup below at Fish Creek Bridge, hitch a ridge, or do a 2 mile road walk back to your ride. Enjoy!
