Start from the saddle between the two Tangen Towers (a short bushwhack from the Royal Arch Trail). The East Face is about 300 feet long, and about the only place to belay is a flake around 160 feet. The first pitch is only 4th class or so, but the second is steeper and comprises the crux.
You can walk off the summit, then go down north of the Upper Tangen Tower, back to the saddle where you started. Do not try to descend south of the Upper Tangen Tower (between it and the 5th Flatiron), this is 5th class.
Pro and even belay anchors are scarce on this route. A light rack is all you will find use for.
